Abstract

Numerical procedure for the development and implementation of a new elastoplastic constitutive model for cohesionless granular materials is presented in the paper. The presented model is based on the hyperbolic failure envelope developed using the theory of incremental plasticity. The governing parameter method (GPM) is used for implicit integration of constitutive relations. The developed algorithm is implemented in the general-purpose finite element program PAK designed for the static, dynamic, linear and non-linear analysis. The model is calibrated and verified through numerical simulation of triaxial test and direct shear test.
