摘要：

The dynamic plastic buckling of annealed OFHC copper cylindrical shells is treated by experiment. finite element code calculation, and analysis. Initial velocity imperfections of the impulsive loading were obtained from sheet explosive thickness measurements. The Johnson-Cook relation was adopted for the copper. A comparison of the final profiles, their modal content, and amplification functions showed good agreement among experimental, code and analytical results
