| Abstract: | By using theoretical analysis based on the rigid,perfectly plastic material idealization,a comprehensive analysis of dynamic behavior of an infinite long tube beam under a rectangular pressure pulse was made.Special attention was paid to the deformation mechanism,the global deformation and plastic dissipated energy.Complete solutions are obtained for the various magnitudeof load.The results will be valuable in research of dynamic deformation and failure of pipelines subjected to impulsive loading. |
