Abstract
The elasto-plastic and voscoplastic constitutive relations with kinematic strain hardening-softening model for geomaterials are applied to boundary value problems. The constitutive models are based on experimental findings about inherent anisotropies and strain rate dependent properties involved in soils. A generalized return-mapping algorithm is applied to solution methods of the problems. The dynamic relaxation method for static problems and the dynamic analysis for earthquake responses are solved based on finite element methods.
