摘要
For the simulation of the behavior of cohesionless soil an elastoplastic double-surface work-hardening model is used. Algorithms for the implicit integration of the rate equations and their consistent linearization are presented. The modified projection algorithm introduced in this paper allows for large load increments compared to the algorithm which follows a classical return mapping approach.
