A study has been made of methods of adapting constitutive equations for granite to numerical computations of wave propagation. The constitutive equations considered are the so-called capped model, which incorporates a strain-hardening surface to control dilatency and a stationary fracture surface. Difficulties have been encountered in some instances when this model has been used for ground shock computations because the model was unproperly coded. This report describes two acceptable methods of coding the model and the results of some test cases which will help reveal errors in the future where similar complicated constitutive equations are being coded for the first time.
