摘要：

Coupled particle-finite element methods have been suggested as an approach to modeling particular impact problems not well suited to simulation with conventional Eulerian, Lagrangian, or particle codes. An alternative hybrid particle-finite clement technique has been developed, in which particles are used to model contact-impact and volumetric deformation while finite elements are employed to represent interparticle tension forces and elastic-plastic deviatoric deformation. The method has been implemented in a three dimensional code and applied to simulate representative hypervelocity impact problems. (C) 1999 Elsevier Science Ltd. All rights reserved.
