Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]
As with tension testing, there exist a variety of methods for specimen attachment and loading when subjecting materials to torsion on a SHPB. One way of applying loading called the stored-torque method involves clamping the midsection of the incident bar while a torque is applied to the free end. The incident wave is created by suddenly ...
In materials science and solid mechanics, biaxial tensile testing is a versatile technique to address the mechanical characterization of planar materials.It is a generalized form of tensile testing in which the material sample is simultaneously stressed along two perpendicular axes.
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
The jaws of the machine must align with test specimen so as soon as the test gets started the long axis of the test specimen will be aligned with the direction of the applied tension. The machines grip on the test specimen must be 63 mm (2.5 in). The code specifies what needs to be recorded from the test such as material used, material ...
Barcol hardness test, for composite materials; Tensile testing, used to obtain the stress-strain curve for a material, and from there, properties such as Young modulus, yield (or proof) stress, tensile stress and % elongation to failure. Impact testing Izod test; Charpy test; Fracture toughness testing Linear-elastic (K Ic) K–R curve
Rising Step Load Testing (or RSL testing) is a testing system that can apply loads in tension or bending to evaluate hydrogen-induced cracking (also called hydrogen embrittlement). It was specifically designed to conduct the accelerated ASTM F1624 [ 1 ] step-modified, slow strain rate tests on a variety of test coupons or structural components.
In surface science, the du Noüy ring method is a technique for measuring the surface tension of a liquid. This technique was proposed by Pierre Lecomte du Noüy in 1925. [1] The measurement is performed with a force tensiometer, which typically uses an electrobalance to measure the excess force caused by the liquid being pulled up and ...
