Abstract:

The non-linear elasto-plastic response of a clamped flat plate to a typical air shock wave were investigated. The nonlinear effects to the plate responses due to the material and geometric nonlinearity were studied. In this study, 1 the necessity of the modification of old armored vehicles was reviewed and 2 the NASTRAN code was employed in this investigation, 3 the theoretical background of the nonlinear transient analysis was described, 4 a step by step procedure of analyzing the dynamic load problem by shock wave using NASTRAN code was developed, and 5 sensitivity analyses were performed and also difficulties associated and the nonlinear analysis were described.
