Implementation and Application of the P-alpha Equation of State in the DYSMAS Code

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.Naval Surface Warfare Center Dahlgren Div VA is the author of 'Implementation and Application of the P-alpha Equation of State in the DYSMAS Code', published 1996 under ISBN 9781423577751 and ISBN 1423577752.
