==Description (Materials Science)==

In materials science, the '''strength''' of a [[material]] refers to the material's ability to withstand an applied [[stress]] without failure. Yield strength refers to the point on the engineering stress-strain curve (as opposed to true stress-strain curve) beyond which the material begins deformation that cannot be reversed upon removal of the loading. <u>Ultimate strength</u> refers to the point on the engineering stress-strain curve corresponding to the maximum stress. The applied stress may be tensile, compressive, or shear.

The applied stress may be tensile, compressive, or shear.

Strength is considered in terms of compressive strength, tensile strength, and shear strength, namely the limit states of compressive stress, tensile stress and shear stress, respectively. The effects of [[dynamic]] loading is probably the most important [[practical]] part of the strength of materials, especially the problem of [[fatigue]]. Repeated loading often initiates brittle cracks, which grow slowly until failure occurs.

Repeated loading often initiates brittle cracks, which grow slowly until failure occurs.

However, the term strength of materials most often refers to various methods of calculating stresses in structural members, such as beams, columns and shafts. The methods that can be 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 or ultimate) strength. For example failure in buckling is dependent on material stiffness (Young's Modulus).[http://en.wikipedia.org/wiki/Strength_of_materials]
