Elastic deformation continues until the yield stress of the material if it is ductile, after which the material plastically deforms. A brittle material fractures before any plastic deformation occurs ...

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 ...

Young's modulus for Polythene, cross-linked by pile irradiation, has been measured by both static and dynamic means. Below about 115° C (the usual melting-point) the modulus decreases with temperature ...
