The SHANSEP MC model (Stress History and Normalized Soil Engineering Properties) constitutes a soil model implemented in PLAXIS, intended for undrained soil loading conditions. It is based on the linear elastic perfectly-plastic Mohr-Coulomb model, but modified such that it is able to simulate potential changes of the undrained shear strength su (cu) based on the effective stress state of the soil. It takes into account the effects of stress history and stress path in characterizing soil strength and in predicting field behaviour.
