A finite element method for gradient elasto-plastic continuum in which the yield strength of strain hardening/softening materials not only depends on the effective plastic strain but also on its Laplacian is presented. The consistent integration algorithm to update the stress and the internal state

This paper presents a framework to describe a mixed element method in the context of pressure-dependent elastoplasticity at moderate ΓΏnite strain. A mixed strain element with one-point quadrature and hourglass control at moderate ΓΏnite strain is developed on the basis of the Hu-Washizu principle and
## Abstract Two finite element formulations are proposed to analyse the dynamic conditions of saturated porous media at large strains with compressible solid and fluid constituents. Unlike similar works published in the literature, the proposed formulations are based on a recently proposed hyperela
