Optimization analysis for the typical details of ship structures

In this paper,two kinds of typical details in ship structures will be researched.One kind of detail is the longitudinal through the deck transverse,another is the longitudinal traversing the stiffener.Based on a series of initial design sizes,we create and analyze the finite element models of research objects with the ABAQUS which is a large generally used finite element software.In view of different complementary plate forms and different stiffener forms,we shall compare the stresses between these typical details,so that we can research the influences on the stress distribution because of different styles of the local structures.We can also analyze the maximum stress of each kind of typical detail under load and give the variation percentage of stresses between these joints.Besides,we will propose the optimized forms so that it could provide actual engineering reference.
