In the mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. The field of strength of materials deals with forces and deformations that result from their acting on a material. A load applied to a mechanical member will induce internal forces within the member called stresses when those forces are expressed on … WebbTheoretical Single Crystal Strength There are two modes possible modes of plastic deformation in tension: cleavage and shear. Cleavage is movement of two portions of the crystal toward either the tension directions, away from the cleavage plane.
