Abstract:Cylindrical shell structure is widely used in marine structure and submarine structure.In order to investigate the response of this structure under impact action and the effect of impact angle on response,the numerical simulation of a double cylindrical shell structure impacted by an object under different loading cases is carried out by MSC.Dytran,an analysis code for nonlinear,dynamic behavior of structure.The damage deformation and energy absorption of cylindrical shell structure as well as the impact force are analyzed in this paper.The results of the calculation are useful to the research and design work of cylindrical shell structure.
Keywords:impact  double cylindrical shell structure  impact angle  numerical simulation
