| Abstract: | Impact/penetration process is nonlinear dynamic problem with failure. Theories and algo- rithms related to that process such as nonlinear material constitute model, contact algorithm, material failure pattern etc are formulated. The basic idea and methods for cluster-based parallel finite element method are explored. The application sample illustrate that the proposed equations and parallel idea are effectively to analyze impact/penetration problem. |
