Title
A High-Cycle Accumulation Model for Sand (Niemunis et al., 2005)
Description
A high-cycle explicit model for the accumulation of strain in sand due to small cyclic loading. The dependence of the accumulation rate on stress, void ratio, cyclic history and the type of loading is considered. In particular, the ovality and the polarization of the strain path during a cycle are taken into account.
