Abstract: Impact/penetration process is nonlinear dynamic problem with failure. Theories and algorithms 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.
