摘要：
The material point method (MPM) fully takes the advantages of both Lagrangian method and Eulerian method, and can be capable of simulating high explosive explosion problems and impact problems involving large deformation and multi-material interaction of different phases. In this paper, MPM is extended to simulate the explosively driven metal problems, and two typical explosive/metal configurations, open-faced sandwich and flat sandwich, are analyzed in detail using MPM, and numerical results are compared with Gurney solution and its corrections. Based on our MPM results, a new correction to Gurney solution is proposed to account for the lateral effects for flat sandwich configuration. MPM provides a powerful tool for studying the explosively driven metal and other explosive problems. (C) 2010 Elsevier Ltd. All rights reserved.
