The ability to resist plastic deformation and fracture under the action of external loads is called strength. According to the nature of the external force, the main yield strength, tensile strength, compressive strength, flexural strength, etc., is commonly used in the yield strength and tensile strength, these two strength indicators can be measured by tensile test.

Strength refers to the ability of the parts to withstand the load after the occurrence of fracture or exceed the allowable limit of residual deformation. That is to say, strength is an important indicator to measure the bearing capacity of the part itself (that is, the ability to resist failure). Strength is the basic requirement of mechanical parts and components. The strength of mechanical parts can be divided into static strength, fatigue strength (bending fatigue and contact fatigue, etc.), breaking strength, impact strength, high temperature and low temperature strength, and creep, bond strength and other projects in the corrosive conditions. The strength of the experimental study is a comprehensive study, mainly through its stress state to study the stress state of the parts and the conditions and timing of failure prediction.
