The stress model of the hybrid finite element formulation is applied to the analysis of quasi-static, gradient-dependent elastoplastic structural problems. The finite element approximation consists in the direct estimate of the stress and plastic multiplier fields in the domain of the element and of

Based on Hellinger}Reissner functional and with the inclusion both of displacements and stresses, a hybrid stress formulation of dynamic "nite element method is derived in this paper. In this formulation, the displacements are separated into zeroth displacement modes and high-order incompatible dyna
