Abstract: This report is the fifth in a series concerning the development and evaluation of variable moduli material models and their application to ground shock calculations for soil type media. Previous reports have presented the details of several variable moduli models and a fit of a particular model to McCormick Ranch Sand. In addition, a series of theoretical solutions have been obtained for code checking purposes. These include the steady state solution for an advancing step pressure on a half-space of a variable moduli material. This report presents a comparison of the numerical results obtained with the axisymmetric LAYER code and the plane strain code for the plane strain theoretical solutions of Ref. . In each case, the same variable moduli material model was prescribed for the half-space. It is seen that the analytical and numerical results agree quite well, thus indicating that the material models in the codes are performing correctly.
