For example, if we consider isotropic linear elastic materials then the elastic response of the material is described fully by just 4 inter-related properties: Poisson’s ratio, Young’s modulus, shear ...

Abstract: Constitutive or material models provide a mathematical description of how solids respond to mechanical stimuli. For example, an isotropic linear elastic constitutive model describes a ...

The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

The diagrams opposite show stress-strain curves for a linear elastic material such as a metal (top) and a non-linear elastic material such as rubber (bottom). If these materials are taken to some ...
