极端变形问题的物质点法研究进展
Recent progress of material point method for extreme deformation problems
摘要
Abstract
By employing both the Lagrangian and Eulerian descriptions,the material point method (MPM) discretizes a material domain into a set of particles (Lagrangian description) moving in a grid fixed in the space (Eulerian description).Thus,the MPM combines the advantages of both the Lagran-gian methods and Eulerian methods,which makes MPM especially effective in modelling problems with extreme deformation such as impact and explosion problems.The research achievements of our group on MPM algorithms for impact,explosion,fluid-structure interaction and other problems with extreme deformation are systematically summarized in this paper.The three-dimensional parallel explicit simulation software MPM3D developed by our group is briefly introduced.The applications of MPM3D in hyper-velocity impact,perforation,explosion,slope failure,metal cutting,and fluid-structure interaction problems are described as well.关键词
