Title: Dynamic Simulation of Cylinder Shell under Underwater Explosion Load
Abstract: Cylinder shell is an important component of ship and submarine and structure of ocean engineering.Studying its response to underwater explosion load is very important for increasing the lifecycle of structure.The experiment of dynamic effect of ship structure produced by underwater shock and explosion bubble has been numerically simulated with LS-DYNA.And dynamic responses of different material and different parameter composite cylinder shell to underwater explosion load are analyzed.The results show that composite has higher anti-impact capability than steel,copper and aluminum and composite with smaller elastic modulus has higher anti-impact capability.The anti-impact can be calculated simply and quickly with this method which provides some references for design of ship structure.
