Second gradient elasto-plastic models for geomaterials
In this article we present a method for the construction of 2nd gradient elasto-plastic models for geomaterials. In order to model the behavior of quasi-brittle solids in particular we will use here the so-called “kinematic hardening” approach and we extend it to the softening regime by resorting to a 2nd gradient approximation of a non-local hypothesis for the hardening parameter. By utilizing Mindlin's continuum approach, and the virtual work equation we formulate finally the basic field equations and a set of “natural” boundary conditions.
