In this paper an application of boundary-layer computing for the nonNewtonian rate type impact hardening and share thinning phenomenon are discussed. The numerical scheme yields the convergent finite element analysis (FEA) solution and stable semi-discrete GalerkinRunge-Kutta(G-RK) iteration. To develope the passive protection model based on the non-recover solid metal (phase1) impact, we are deepening our knowledge of soft material recover protection (phase2) concept. The high performance computing (HPC) tool enabled us to carry out the research on the passive safety analysis with engineering computing.
