Mechanical properties of materials: the ability of materials to resist deformation or failure under external forces, including strength, plasticity, elasticity, brittleness, fracture toughness, hardness, etc.
Mechanical property tests of materials: tensile, compressive, bending, shear, torsion, impact, fatigue, creep, endurance, relaxation, wear, hardness and other tests. In material testing, especially static testing of metal materials, tensile testing at room temperature is often used. Because metal tensile testing is relatively easy to conduct and the data obtained can reflect the mechanical properties of the tested material, it is widely used.
