Abstract

A grid-characteristic numerical method based on tetrahedron grids is applied to simulate wave processes in a composite material under the action of a pulsed shock load. An approach is proposed to increase the approximation order of the method on an unstructured grid in the three-dimensional case. Computational results for load pulse propagation in a three-layer composite are presented.

当使用非结构化计算网格时，复合样品中波动过程计算的近似阶数增加

采用基于四面体网格的网格特征数值方法，模拟了复合材料在脉冲冲击载荷作用下的波动过程。提出了一种在三维情况下提高该方法在非结构网格上的近似阶数的方法。给出了载荷脉冲在三层复合材料中传播的计算结果。
