A Critical State Sand Model with Elastic-Plastic Coupling

摘要：

　　Experimental studies have revealed that plastic strains change the elastic properties of granular soils.This observation is an elastic-plastic coupling phenomenon which is considered here through the dependence of a free energy function to a proper hardening parameter.It is shown that implementation of the resulted hyperelastic model in a critical state bounding surface plasticity platform leads to more reasonable simulations.
