Webstrain hardening. The ordinate of point B is called the yield stress by analogy with the response of concrete samples. The maximum ordinate of the curve (Point C) that marks the transition between strain hardening and softening is called the unconfined compressive strength of the rock and is denoted as Co or qu. Failure takes place continuously ... WebThe hardening curve must describe the cohesion yield stress as a function of plastic strain and, possibly, temperature and predefined field variables. In defining this dependence at finite strains, “true” (Cauchy) stress and …
