マーカ粒子特性有限要素法による固体の大変形解析(OS8e メッシュフリー/粒子法)

抄録

A novel approach of the Eulerian finite element method for large deformation problems of solid is proposed in this paper. A marker particle method is employed to evaluate the Lagrangian motion of materials and advection of internal variables. 4hhe equation of motion is approximated by the finite element method with fixed spatial mesh, which also gives spatial derivatives such as strain.
