Tensile & Bend Testing

A tensile test measures the resistance of a material to a static or slowly applied force. A machined specimen is placed in the testing machine and a load is applied. A strain gauge or extensometer is used to measure the elongation. The stress obtained at the highest applied force is known as Tensile Strength. The Yield Strength is the stress at which a prescribed amount of plastic deformation (commonly 0.2%) is produced. Elongation describes the extent to which the specimen is stretched before fracture. Information regarding the strength, stiffness, and ductility of a material is obtained from a tensile test. Other variations of the tensile testing include Room Temperature, Low Temperature, Elevated Temperature (ASTM E21), Shear, Temperature and Humidity, Combined Tension and Compression, Through-Thickness, True Strain, Notched Tensile and R (ASTM E646) & N (ASTM E517) values.


All tests at TCR Arabia are performed in line with the ASTM E8, ASTM A370, ASTM B557 and IS/ BS Standards. TCR has the expertise to determine the mechanical properties of materials and resolve a wide variety of technical problems for the industry:



Bend Test

This procedure that determines the relative ductility of metal that is to be formed (usually sheet, strip, plate or wire). It is also used to determine the soundness and toughness of metal (after welding, etc.) The specimen is usually bent over a specified diameter mandrel. The four general types of bends are free bend, guided bend (ASTM E190), semi-guided bend (ASTM E290) and wrap-around bend.


Compression Test

This is a method for assessing the ability of a material to withstand compressive loads. The test is commonly used as a simple measure of the metal workability, particularly in forging and similar bulk deformation processes. Engine mounts, bolster springs, cast products, and similar components are tested to determine load versus displacement. 


Ring Flaring Test, ASTM A513

This procedure tests the ability of a section of a tube, approximately 4" in length to flare (with a tool having a 60° included angle). This is done through the tube as the mouth of the flare expands to 15% of the inside diameter without cracking or indicating any flaws.


Ring Flattening Test, ASTM A513

A tube sample, 4" - 6" in length is flattened between parallel plates with the weld 90° from the direction of applied force until opposite walls of the tubing meet. Applications for this test along with the flaring test, include situations where round tubing is to be formed into other shapes.

Tensile & Bend Testing


Impact Testing

The impact test (ASTM E23 and IS/ BS Standard) is a method for evaluating the toughness and notch sensitivity of engineering materials. It is usually used to test the toughness of metals but similar tests are used for polymers, ceramics, and composites. Metal industry sectors include Oil and Gas, Aerospace, Power Generation, Automotive, and Nuclear.

The notched test specimen is broken by the impact of a heavy pendulum or hammer falling at a predetermined velocity through a fixed distance. The test measures the energy absorbed by the fractured specimen. 


Charpy Impact Test

A test specimen is machined to a 10mm x 10mm (full size) cross-section, with either a "V" or "U" notch. Sub-size specimens are used where the material thickness is restricted. Specimens can be tested down to cryogenic temperatures. 


IZOD Impact Test

The test specimen is machined to a square or round section, with either one, two or three notches. The specimen is clamped vertically on the anvil with the notch facing the hammer.


Keyhole Impact Test

The steel casting industry uses this type of specimen frequently. The notch is machined to look like a keyhole. It is tested in the same manner as the "V" and "U" notch.

Impact Testing



Hardness Testing measures a material’s strength by determining resistance to penetration. The hardness test is extremely useful in material selection because it provides a hardness value, which indicates how easily a material can be machined and how well the material will wear.  It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation. Simply put, when using a fixed force (load) and a given indenter, the smaller the indentation, the harder the material.


Brinell, ASTM E10 and IS/ BS Standard

This is a simple indentation test for determining the hardness of a wide variety of materials. The test consists of applying a prescribed load, usually between 500 kg and 3000 kg, for a specified time (10-30 seconds), using a 5 or 10mm diameter tungsten carbide ball on the flat surface of a metal sample. 


Knoop, ASTM E384 and IS/ BS Standard

The Knoop indenter has a polished rhombohedral shape with an included longitudinal angle of 172° 30´ and an included transverse angle of 130° 0´. The narrowness of the indenter makes it ideal for testing specimens with steep hardness gradients and coatings. Knoop is a better choice for hardness testing of hard and brittle materials. 


Rockwell, ASTM E18 and IS/ BS Standard

This test differs from the Brinell test in the shape of the indenter and in the manner that the number is determined. The Rockwell number represents the difference in depth penetration between two loads. There are two types of Rockwell; Rockwell and Superficial Rockwell. The difference between the two is in the minor and major loads applied to the specimen. The indenter used may be a diamond cone or a hardened ball, depending principally on the characteristics of the material being tested. 


Micro hardness, ASTM 3384 and IS/ BS Standard

A micro indentation is made on the surface of a metal sample. The hardness number is based on the measurements of the indent formed on the surface of the test specimen.


Portable Hardness, ASTM E110 and IS/ BS Standard

Facility for Portable hardness testing using rebound-type digital hardness tester is available for carrying out hardness testing at the site. This is particularly useful for large objects and where cutting the sample is not possible.


This testing is similar to Brinell, in which a defined indenter is pressed into a material. Once the indenting force is removed, the resulting indentation diagonals are measured. Micro indentation Vickers is per ASTM E384 and Macro indentation Vickers is per ASTM E92. 


Hardness Testing


Nick Break

The principle of this test is to break the sample through the weld metal in order to examine the fractured surface. Applying a three-point bend load induces the fracture. The fractured surface is then examined and the type and location of any weld defect are reported. 


The procedure consists of performing a chemical analysis and/or mechanical tests with metallography to provide data for the determination of weldability. Weld Engineering provides additional support and recommendations for material usage. If necessary, trial welds can be fully tested and examined to provide final data.

Nick Break and Weldability

Nick break testing is another simple process that lends itself to learning welding, due to its speed and very low cost. It is also used in production runs, where quality is monitored at intervals throughout production. The principle behind it is to take a sample piece, partially cut through it and then break the remainder off. This allows one to ‘see inside the weld’. Various defects and faults can be easily seen by visual inspection including lack of fusion, porosity, slag inclusions etc. 

Nick Break and Weldability


Component Testing and Fasteners

Component Testing and Fasteners

Testing components take on many forms depending on the application and the conditions present in service. TCR routinely tests components under fatigue, vibration, shock, pressure, high and low temperatures, humidity, solar, corrosion, impact, hydrostatic pressure and altitude conditions. Test capacity can vary from small (several inches in size) to large (vehicle size). Test fixtures can be made in-house via 3D drawings or FE models.

Frequently tested components include automotive parts and assemblies (i.e. axles, engine cradles, transmission shafts, shock absorbers, doors, locking enclosures, connecting rods as engine mounts and crankshafts) electronic displays, communication devices, packaged products, pressure vessels, pipes, and building products such as fascia and structural products. Aerospace components, in particular, electronic devices and landing gear assemblies are also tested.


Dynamic Loading

Dynamic loading takes on many forms like impact, vibration, shock, fatigue and high strain rate to name a few. TCR is capable of performing many forms of dynamic tests on specimens, prototypes, and varied assemblies.


Fasteners - Wedge, Axial, Proof Load and Torque

Fasteners of all sizes used in every application are critical to the integrity of structures and finished components. In addition to dimensional, chemical composition and metallurgical properties, Mechanical Testing is of paramount importance in determining compliance with specifications and fitness for different purposes.



The wedge tensile strength of a hex or square-head fastener, socket-head cap screw or stud is the tensile load that the product is capable of sustaining when stressed with a wedge under the head. The purpose of this test is to obtain the tensile strength and to demonstrate the head quality and ductility of the product.



The Axial tension of fasteners is tested in a holder with a load axially applied between the head and a nut, or in a suitable fixture.


Proof Load

Proof Load testing of a nut is assembled on a hardened, threaded mandrel or a test bolt, using the tension or compression method. A specified proof load is applied on the nut against the nut. The nut should resist this load without stripping or rupturing and should be removable from the test bolt or mandrel by hand after the load is released.



The most common way to estimate clamping force is to observe the amount of torque applied to the fastener. This procedure assumes that the relationship between torque and tension is known. The most common measurement tools are handheld torque wrenches.


Creep & Stress Rupture Test

Creep is high-temperature progressive deformation at constant stress. The high temperature is a relative term that is dependent upon the materials involved. Creep rates are used in evaluating materials for boilers, gas turbines, jet engines, ovens or any application that involves high temperatures under load.


The understanding of the high-temperature behavior of metals is useful in designing failure resistant systems. A creep test involves a tensile specimen under a constant load maintained at a constant temperature and measurements of strain are then recorded over a period of time. Like the Creep Test, Stress rupture test involves a tensile specimen under a constant load at a constant temperature. Stress rupture testing is similar to creep testing apart from the utilization of higher stress than that of creep testing. Stress rupture tests are employed to find out the time it takes for failure and hence stress rupture testing is always continued until failure of the material occurs. Data is plotted similar on a graph and a straight line or best-fit bend is normally obtained at every temperature of interest. The Stress Rupture test is used to determine the time for failure and elongation.


TCR has the facility for conducting Stress rupture test, Creep rupture/Creep test & Stress relaxation test as per ASTM/IS/ISO specifications.


Creep and Stress Rupture Test

Fatigue and Fracture Toughness Testing

Fatigue & Fractue Toughness

Fatigue testing applies cyclic loading to a test specimen, to understand its performance under similar conditions when in actual use. The load application can either be a repeated application of fixed load or simulation of in-service loads. The load application may be repeated millions of times and up to several hundred times per second.


Many engineering metals and alloys display embrittlement at reduced (below sub-zero) temperatures. Structures fabricated from them fracture or shatter unexpectedly at low temperatures when loaded to stress levels at which performance would otherwise be satisfactory at room temperature. To avoid such incidents, the selection of the right material can be done by testing them for their mechanical properties.


In recent years, tremendous interest has been generated in fracture toughness testing based on linear elastic fracture mechanics. Fracture mechanics principles have been used to quantify safety factors in structural design, taking into account crack propagation and/or brittle fracture. Most structural members, components, vessels, piping, aviation, and aerospace are designed according to analysis criteria that guard against failure. CTOD testing requirement is most common in welded coupon as recommended in ONGC, EIL, DNV & API specification.


TCR Arabia has expanded its capabilities to include fatigue, fracture toughness, CTOD and high-temperature tensile testing with the addition of two fatigue systems with the Universal Testing Machine which has a capacity of 50 kN and 250 kN. The versatile Servo-hydraulic systems will allow the mechanical testing laboratory to perform numerous types of fatigue tests on different specimen sizes and orientations, in the temperature range from ambient to 1000° C. TCR has the capability of applying linear displacements, utilizing linear and hydraulic actuators. Comparison fatigue testing of OEM and alternate source parts can also be performed to demonstrate equivalency of fatigue life.

TCR Arabia provides a diverse range of capabilities following ASTM/BS/ISO Specifications. Both ASTM E606 (Low-cycle fatigue, strain-controlled Fatigue Testing) and ASTM E466 (Load-controlled Fatigue Testing – High or Low-cycle fatigue testing) have been widely in use at TCR Arabia. Tests are also conducted for TMT RE-BAR, COUPLERS Fatigue test (100 Cycles test & 2 million Cycles test) as per IS 16172-2014. 


Fracture Toughness Testing: Fracture toughness determines the amount of stress required to propagate an existing flaw or defect in specific materials. Since traditional methods of destructive testing cannot always predict how a material will behave during defect fracture, toughness is very important at the design stage.



Crack-Tip Opening Displacement Testing: Crack-tip opening displacement is used as a type of fracture-toughness testing to determine if a material is appropriate for strenuous working conditions. CTOD testing is the measure of deformation, prior to failure in pre-cracked samples. This type of test is a variation of fatigue testing that has load rates more as representative of in-service conditions.
