MetadataShow full item record
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 with the nonlinear analysis were described.
