Mechanics of materials, also called strength of materials, is a subject which deals with the behavior of objects withstanding stresses and strains. This theory was established on the basis of mathematical modeling in first and second principal stress, specifically because types of stress state in construction parts such beam and shell are possible to approximate as one or two dimensional one. An important founding pioneer in mechanics of materials was Stephen Timoshenko.
The study of strength of materials often refers to various methods of calculating stresses in structural members, such as beams, columns and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes may take into account various properties of the materials other than material yield strength and ultimate strength; for example, failure by buckling is dependent on material stiffness and thus Young's Modulus.
