Extension of Mohr-coulomb model into state dependent softening of sand and its application in large deformation analysis
Extension of Mohr-coulomb model into state dependent softening of sand and its application in large deformation analysis
State transformation is common in soil shearing problem and causes much difficulty in soil description in numerical simulation. For characterizing the state transformation of sand, dilatancy angle and friction angle are linked with soil state parameter, i.e. the difference between current void ratio and void ratio at critical state. Further, state dependent dilatancy angle and friction angle are introduced into classical MC model. The new model shows robust stability in large deformation analysis and offers prediction matching the softening/hardening behavior of sand in laboratory tests, as well as the penetration resistance of spudcan into soil.

Abstract
State transformation is common in soil shearing problem and causes much difficulty in soil description in numerical simulation. For characterizing the state transformation of sand, dilatancy angle and friction angle are linked with soil state parameter, i.e. the difference between current void ratio and void ratio at critical state. Further, state dependent dilatancy angle and friction angle are introduced into classical MC model. The new model shows robust stability in large deformation analysis and offers prediction matching the softening/hardening behavior of sand in laboratory tests, as well as the penetration resistance of spudcan into soil.
