The dynamic response of cylindrical shells subjected to side-on underwater explosions

Abstract

Two studies were performed to enhance the understanding of phenomena occurring in shell structures subjected to side-on underwater explosions. In the first, a numerical analysis was performed to investigate the non-linear response of cylindrical shells subjected to near-field side-on underwater explosions. In the second study, a numerical analysis of a cylindrical shell subjected to a far-field underwater explosion was compared with the results from an underwater explosion test. Sensitivity analyses were performed to determine the relative importance of various physical and numerical modelling factors.
