Numerical Simulation of Multi-Dimensional Wave Processes
A. The general WFEM approach proposed by Shorr (1997, 1999) and described below is suitable for analysis of any multi-dimensional wave processes. For the sake of simplicity and clearness, the methodology is presented in application to 2-D waves and a Cartesian x, y-coordinate system. Strain is assumed to be elastic and small; element rotation is also believed to be small.
