โœฆ Synopsis

A mixed/hybrid FE formulation for the solution of elasto-viscoplastic problems under dynamic loading conditions is presented. The constitutive equations under considerations are those of Chaboche. The spatially semi-discretized system of ordinary differential equations is numerically integrated in time by means of a midpoint type algorithm. A layer-model is developed which enables the application of the proposed methods in shell or plate theory. Numerical examples demonstrate the efficiency of the proposed method.

A mixed formulation of the finite element method is used to establish a higher-order incremental method for the solution of parabolic equations. The displacement and velocity fields (in the terminology of Solid Mechanics) are approximated independently in time using a hierarchical, adaptive basis. T

In this paper we propose a dual-mixed hybrid formulation capable of treating under a unified framework both compressible and incompressible problems in continuum mechanics. A theoretical analysis of the method is carried out and optimal error estimates are derived for both mixed and hybrid variables
