Underwater shock-induced responses of submerged cylindrical structures

Abstract

The non-linear elasto-plastic responses of a submerged cylindrical shell to an underwater shock wave have been investigated. Using the EPSA (Elasto-Plastic Shell Analysis) code, the gross responses of homogeneous and ring-stiffened shells were evaluated, The relevant parameters have been displayed and evaluated using PATRAB-G color graphics system. An interface module was developed between EPSA and PATRAN-G. The deformations and von Mises stresses throughout the shell have been qualitatively evaluated.
