Analytical and numerical relaxation results for models in soil mechanics

Abstract A variational model of pressure-dependent plasticity employing a time-incremental setting is introduced. novel formulation the dissipation potential allows one to construct condensed energy in variationally consistent manner. For one-dimensional problem, an explicit expression for quasiconvex envelope can be found which turns out essentially independent original yield surface. The problem extended higher dimensions empirical Numerical simulation exhibits well-posed behavior showing mesh-independent results.
