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.
