The resistance of materials also called material mechanics.It is a subject that deals with the behavior of solid objects subject to tensions and tensions. The complete theory began with the consideration of the behavior of members of one and two dimensions of structures, whose stress states can be approximated as two-dimensional, and then generalized to three dimensions to develop a more complete theory of elastic and plastic behavior of materials. An important pioneer founder in material mechanics was Stephen Tymoshenko.
The study of the strength of materials often refers to various methods of calculating stresses and tensions in the structural members, such as beams, columns and shafts. The methods used to predict the response of a structure under load and its susceptibility to various failure modes take into account the properties of materials such as their yield strength, maximum strength, Young's modulus and Poisson's ratio; In addition, the macroscopic properties of the mechanical element (geometric properties), such as its length, width, thickness, boundary limitations and abrupt changes in geometry, such as holes, are considered.
