IMAGE OF PARTICLE MESH
The material properties used in this study generally follow that of Y. Wen, et. al, with the exception of the use of a Mie-Grunieson formulation for the equation of state in contrast to the use of a polynomial form. As seen in Appendix A, even through large changes in material density, the pressure found through the Mie-Grunieson EOS approximately matches that of a polynomial formulation using the same material properties in each. Since the Mie-Grunieson is already built into Uintah and is more commonly used in shock-based problems, this formulation was used for this study.The material properties used in the MPM verification studies are tabulated below.
