An Approach to Optimization In Ship Structural Design Using Finite Element And Optimization Techniques

This paper explores a practical application of shape optimization in combination with finite element analysis in ship structural design. For an improved structural design of ships, different optimization techniques are outlined. A basic problem of linear strength analysis is solved to validate the proposed optimization strategy. Parametric models are used to accommodate changing dimensions during the optimization process. As a practical example, a floor of a doublebottom structure is optimized with respect to weight.
