Tensile strength testing of metals

Author:admin Published:2015-03-25 19:17:52
  Ability to resist plastic deformation and fracture of metallic materials under external loading effect called strength. Different according to the nature of the external force, there are yield strength, tensile strength, compressive strength, flexural strength, widely used in engineering is the yield strength and tensile strength, the strength of these two indicators can be measured by a tensile test.
  Strength refers to the part after the fracture resistance under load or exceed the ability of the residual deformation of the allowable limit. In other words, is an important indicator of the strength of the part itself carrying capacity (ie, the ability to resist failure) of. Strength is the basic requirement to be met first mechanical parts. Strength of the mechanical parts can generally be divided into static strength and fatigue strength (bending fatigue and contact fatigue, etc.), breaking strength, impact strength, high temperature and low temperature strength, corrosion under conditions of strength and creep, bonding strength and other projects. Research on the strength of the comprehensive study, mainly to study the situation by force components and to predict the failure of the conditions and timing of the destruction by the stress state.
