Non-linear transient response of flat plate to air shock wave.
nonlineartransie00leej.pdf (6.618Mb)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 with the nonlinear analysis were described.
