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 ...

This webinar investigates the advantages and usage of AFM on studying the mechanics of soft materials from Bruker. AFM methods to obtain absolute values of elastic modulus are described. This is ...

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 ...
