Yield strength steel

The elastic limit or also called the elasticity limit, is the maximum stress that an elastic material can withstand without suffering permanent deformations. In other words, it is when a material exceeds a limit when a force is applied to it where it no longer recovers its original shape.

For metals that have a significant straight-line section on the load / strain diagram, the elastic limit is approximately equal to the proportional limit. There are many applications where it is required high elastic limit steels such as: cranes, bridges, docks, building structures etc.

The elastic limit or yield point is the maximum stress that an elastoplastic material can withstand without suffering permanent deformation.

The elastic limit of a material is usually calculated using Young's Modulus (longitudinal modulus of elasticity)
