Abstract

Computational techniques, which preserve the objectivity of incremental constitutive relations, for finite elastic or inelastic materials, for finite time steps, during which the material elements may undergo finite rotations, are presented. These techniques are useful in finite deformation (finite rotations and finite strain) computational analysis of two as well as three dimensional solids and structures.
