In solid mechanics, elasticity is the property of materials which undergo reversible deformations under applied loads. Solid mechanics is the branch of physics and mathematics that concern the behavior of solid matter under external actions (e. ... In engineering mechanics, deformation is a change in shape due to an applied force. ...

The deformation of a solid is part of the study of solid mechanics. In solid mechanics, a material behaves elastically if it changes shape due to an applied load, and that when the load is removed, recovers its original shape. In solid mechanics theory, every material changes shape when loads are applied to it, though very small loads produce very small deformations. Furthermore, most solid materials will undergo elastic deformation as long as the loads are kept under a certain limit. This limit is known as the elastic limit or the yield strength of the material, and is one way of defining its strength. Solid mechanics is the branch of physics and mathematics that concern the behavior of solid matter under external actions (e. ... In engineering mechanics, deformation is a change in shape due to an applied force. ... The tensile strength of a material is the maximum amount of tensile stress that it can be subjected to before it breaks. ... Yield strength, or the yield point, is defined in engineering and materials science as the stress at which a material begins to plastically deform. ... It has been suggested that Tensile strength be merged into this article or section. ...

Elastic deformation can be either linear or nonlinear. In linear elasticity, the elastic deformation is directly proportional to the applied load. The elasticity of a solid is inversely proportional to its stiffness. Stiffness, when corrected for the dimensions of the solid, becomes modulus of elasticity, which is an intensive property of the material. The stiffness of a structure is of principle importance in many engineering applications, so modulus of elasticity is often one of the primary properties considered when selecting a material. A high modulus of elasticity is sought when deflections are undesirable, while a low modulus of elasticity is required when flexibilty is needed. Stiffness is the resistance of an elastic body to deflection by an applied force. ... In solid mechanics, Youngs modulus (also known as the modulus of elasticity or elastic modulus) is a measure of the Stiffness of a given material. ... An intensive property is sometimes defined as a ratio of two extensive properties. ...
