摘要： When a cylindrical shell is subjected to dynamic implusive loading in radialdirection and foe ratio of radius-to-thickness exceeds a special value. the cylindricalshell will produce elastic dynamic buckling. This paper which is based on foe results ofsome relative experiments, assumes deformation mode and utilizes Lagrange method toanalyse the elastic pluse buckling of a thin cylindrical shell with a finite length under acosine impulse. The dynamic buckling equations are derived and solved by numericalmethod. The results of calculation are compared with some relative calculation resultswhich were obtained by other authors.
