Abstract : This report describes the implementation of the Mie-Gruneisen and P-alpha equations of state in the DYSMAS code. The motivation for these enhancements is to provide an equation of state that treats partially saturated sand. The pores in the P-alpha model are used to simulate the sand pore volume free from water, while the Mie-Gruneisen equation of state accounts for the water-grain mixture. Additionally, the Mie-Gruneisen equations of state provides a means of modeling the equations of state of metals.
