Ключевые слова: finite difference method, elastic wave, Multidimensional problem

Аннотация: This paper presents the extension of the PEM scheme for the case of multidimensional wave problems. This is done on the basis of operator splitting and the PEM scheme for the one-dimensional wave equation given in the previous publication (V. Zalizniak, Commun. Numer. Meth. Engrg. 13 (3) (1997) 163-171). Numerical results for two pПоказать полностьюroblems of wave propagation in comparison with the analytical solutions are given to demonstrate the effectiveness of the proposed method for elastodynamics.
