Tensile strength of common materials
Tensile strength is the critical value of metal transition from uniform plastic deformation to locally concentrated plastic deformation, and is also the maximum bearing capacity of metal under static tensile condition.Tensile strength is the resistance that represents the maximum uniform plastic deformation of the material. Before the tensile specimen bears the maximum tensile stress, the deformation is uniform and consistent, but after exceeding, the metal begins to shrink, i.e. centralized deformation occurs.For brittle materials without (or very little) uniform plastic deformation, it reflects the fracture resistance of the material.It can also be understood that when the steel yield to a certain extent, its resistance to deformation is improved again due to the rearrangement of internal grains. At this time, although the deformation develops rapidly, it can only increase with the increase of stress until the stress reaches the maximum value.Since then, the ability of steel to resist deformation is obviously reduced, and a large plastic deformation occurs at the weakest part, where the section of the specimen rapidly shrinks, necking phenomenon occurs, and even fracture failure occurs.The maximum stress value of steel before tensile f
