Abstract

An optimisation procedure to be used to develop optimised X-80 steel blast tolerant transverse bulkheads is described. Three different structural arrangements have been investigated and optimised. This work has been stimulated by the increased interest in naval platform survivability over the past decade and the development of X-80 steel. 1. Introduction This paper discusses an optimisation procedure for static and dynamic non-linear load cases that must satisfy the design criteria given in Raymond et al. [1] and Raymond etal. [2]. 1.1 X-80 steel X-80 grade steel was initially developed in the mid-seventies for use in the linepipe industry. The characteristics of X-80 steel
