Microscopic Simulations of Shock Wave Propagation in Pseudo-skull

This paper develops a basic numerical scheme for a pseudo-skull matter and shows how to construct a reliable model. First, we solve one dimensional model and shows the solutions, which we cannot expect before numerical calculation. Next we solve two dimensional model and compare the results of one and two dimensional models. From the comparison, we understand the important feature of the propagation of shock wave, i.e., the shock wave goes to directly on a line without spreading into the other dimension in the matter. This means the one dimensional model is useful, since it can give an essential feature of the shock wave. Finally, we show the energy and momen- tum conservation low holds while the calculation.
