Abstract:

A large-strainhigh-deformation rate model for clay-free sand recently proposed and validated in our work 1,2, has been extended to sand containing relatively small less than 15vol. of clay and having various levels of saturation with water. The model includes an equation of state which represents the material response under hydrostatic pressure, a strength model which captures material behavior under elastic-plastic conditions and a failure model which defines conditions and laws for the initiation and evolution of damagefailure in the material. The model was validated by comparing the computational results associated with detonation of a landmine in clayey sand at different levels of saturation with water with their computational counterparts.
