| Abstract: | Under the study of the buckling of the damaged ring-stiffened cylindrical shell subject to underwater explosion loading, the buckling strength of the damaged ring-stiffened cylindrical shell is calculated with MSC. DYTRAN and MSC. NASTRAN. An analysis method for calculating the resi-(dual) buckling strength of ring-stiffened cylindrical shell with those two softwares is advanced. The numerical analysis shows that the prediction agrees fairly well with the experiment results. |
