Numerical Methods for Plasticity and Viscoplasticity of Geomaterials
A numerical method such as a finite element method employing a dynamic relaxation method with the generalized return-mapping algorithm is developed. Elasto-plastic and visoplastic constitutive relations including the effect of a shear band are applied to the geotechnical problems. A kinematic hardening-softening model considering the cumulative deformation by cyclic loading is also developed. Within bounding surface, plastic behavior is assumed and this cyclic elasto-plastic and viscoplastic constitutive models are applied to two dimensional element test simulation of geomaterials. The constitutive model is also applied to dynamic response analysis of embankment dam. The results of finite element analysis are compared with those from the physical experiments and considered to be promising for the prediction of cumulative deformation of soil structures and liquefaction problems.
