2. Tensile test

2.1 The most important test

The tensile test is considered one of the most important of all mechanical tests. This test is used to determine the mechanical properties of a material under various simple stresses to which a mechanical part may be subjected. For this purpose, a specimen is subjected to a progressive tensile stress until failure. The loads and corresponding elongations are recorded on a machine, giving rise to a diagram known as the tensile curve. This curve is used to determine the yield strength, tensile strength, Young's modulus and elongation at break of the material under test.
