DYNAMIC PLASTIC RESPONSE OF CYLINDRICAL SHELLS UNDER GAUSSIAN IMPULSE

The determination of the inelastic response of cylindrical shells under general impulsive loads is of relevance to marine structures such as submarines, in analyzing their slamming damages. The present study is concerned with the plastic response of a simply supported cylindrical shell under a general axisymmetrtic impulsive load. The impulsive load is assumed to impart an axisymmetric velocity to the shell, with a Gaussian distribution along the longitudinal axis of the shell. A simplified Tresca yield condition is used. The shell response is determined for various forms of impluses ranging from a concentrated impulse to a uniform impluse over the entire length of the shell. Conclusions about the influence of geometry of the shell and the spatial distribution of impluse on the plastic behavior of cylindrical shells are presented.
