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