Metal mechanical test, also known as physical mechanical property test, mechanical property is a set of common indicators of metal materials. In the mechanical manufacturing industry, general mechanical parts are used in normal temperature, atmospheric pressure and non strong corrosive medium, and in the use process, each mechanical part will bear different loads. The ability of metal materials to resist failure under load is called mechanical property (or mechanical property). The performance of metal material determines its service range and service life. The mechanical properties of metal materials are the main basis of parts design and material selection. The mechanical properties required for metal materials will be different with different properties of applied loads (such as tension, compression, torsion, impact, cyclic load, etc.). Common mechanical properties include: strength, plasticity, hardness, impact toughness, multiple impact resistance and fatigue limit. Mechanical performance test can be divided into static test and dynamic test. Static test includes tensile test, compression test, bending test, shear test, torsion test, hardness test, creep test, high temperature endurance strength test, stress relaxation test, fracture toughness test (see fracture mechanics analysis), etc. Dynamic test includes impact test, fatigue test (see fatigue; strength), etc.
