Subdifferential-based implicit return-mapping operators in Mohr-Coulomb plasticity
The paper is devoted to the numerical solution of an elastoplastic constitutive initial value problem containing the Mohr-Coulomb yield criterion, a nonassociative plastic flow rule, and a nonlinear isotropic hardening. The constitutive problem is discretized by the implicit Euler method. Instead of the conventional Koiter formulations, we define the plastic flow rule using the subdifferential ...
متن کاملEvaluating the Soil Bearing Capacity Coefficients by Means of a Finite Element Program Based on Elasto - Plastic Mohr - Coulomb Behavior
A finite element program based on elastic –plastic model of Mohr-Coulomb criterion was used to evaluate the bearing capacity coefficients of soil under shallow strip flexible footing . The results were compared with others’ analytical results and it was found that the present study could offer quite consistent and rather precise values for the bearing capacity coefficients . 

The effect ...
متن کاملOn diagonal subdifferential operators in nonreflexive Banach spaces
Consider a real-valued bifunction f defined on C×C, where C is a closed and convex subset of a Banach space X , which is concave in its first argument and convex in its second one. We study its subdifferential with respect to the second argument, evaluated at pairs of the form (x, x), and the subdifferential of −f with respect to its first argument, evaluated at the same pairs. We prove that if...

متن کاملNonconvex Evolution Inclusions Generated by Time - Dependent Subdifferential Operators
We consider nonlinear nonconvex evolution inclusions driven by time-varying subdifferentials 0(t,x) without assuming that (t,.) is of compact type. We show the existence of extremal solutions and then we prove a strong relaxation theorem. Moreover,r we show that under a Lipschitz condition on the orientor field, the solution set of the nonconvex problem is path-connected in C(T,H). These result...
