计算域可变的CEL方法
A CEL method with changeable computational domain
摘要
Abstract
In order to improve the large deformation problem within the Lagrangian domain,a CEL method with the capability of mapping Lagrangian materials to the Eulerian domain was presented.The contact problem in the Eulerian-Lagrangian overlapping region was converted to the multi-materials problem in the Eulerian region.The construction of the CEL method was also simplified.The method was verified by the calculation of two experiments (a steel bullet impacting an aluminous plate experiment and a structure response to the blast wave experiment).It is found that the numerical results agree well with the experimental data.关键词
