Abstract

When an external load is applied to a material, deformation occurs. The concept of “rigid body,” while very useful in a wide range of structural and dynamic engineering applications, is never a true representation of actual materials. This non-rigidity of material gives rise to a dimensional change (strain) in response to the outside mechanical stimulation. If instead it is the dimensional change that is prescribed, then a mechanical stress will be generated in the material. The relationship between stress and strain determines the constitutive response of a material. The simplest form of stress–strain relationship is linear elastic, where the state of strain can be directly obtained from a known state of stress (and vice versa) through a set of elastic constants. More complex behavior such as plastic and time-dependent deformation frequently occurs, depending on the combination of materials, geometry, and loading conditions.
