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 کاملSpherical Cavity Expansion in Material with Densification
LLE Review, Volume 85 15 Introduction Fused silica (SiO2) exhibits some unique features when it is ground or polished. It also densifies permanently under large compressive stresses at room temperature;1–3 up to 15% permanent densification has been observed.2,3 The experimental data for densification from different works, however, are obviously inconsistent,4 which may result from different lev...
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 کاملNumerical Study of Natural Convection in a Square Cavity Filled with a Porous Medium Saturated with Nanofluid
Steady state natural convection of Al2O3-water nanofluid inside a square cavity filled with a porous medium is investigated numerically. The temperatures of the two side walls of the cavity are maintained at TH and TC, where TC has been considered as the reference condition. The top and the bottom horizontal walls have been considered to be insulated i.e., non-conducting and impermeable to mass...
