Limit Deformation Analysis of Rectangular Stiffened Plate to Near-Filed Explosions

Abstract:

Stiffened plate is used widely in ship structure for its high capacity and light weight so studying the limit of deformation of stiffened plates under blast loading has important engineering significance. The blast loading is simplified to triangle with only ascending stage and equivalent stiffness at all directions and every parameter of the stiffened plate are calculated so the maximum deformation can be solved finally. The dynamic response of rectangle stiffened plate under blast loading was simulated by non-linear finite element software and got the maximum deformation of the plate .The simulative results are consistent with the theoretical results. At the same time, the displacement and velocity of all directions at three different points can be got from the simulation and related theoretical derivation is proved correctly by analyzing the simulative results.
