Dynamic Stability of Cylindrical Shells Under Step Loading.

摘要

A study has been made to determine the dynamic stability of an imperfect circular cylindrical shell subject to a step loading in the axial direction. In the analysis,the radial displacement of the shell is approximated by a finite degree of freedom system. To assure that the created model is proper,its static buckling behavior was studied. It was found that the model gives the proper imperfection sensitivity behavior. (Modified author abstract)
