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 … Webbinvestigation of the theoretical strength became possi ble only with the advent of techniques for strength testing of small volumes of the material, in which defects are absent or their concentration is negligible.
