In the previous papers, author presented the Shape Optimization Method to reduce the maximum stress around discontinuous parts of ship structure without inserting thick reinforcement plate by means of finite element method applied to two dimensional stress analysis. In this paper, it is studied how insert plate is effective to the stress concentration around discontinuous parts of ship structure, and a method of determining the optimum shape and the dimensions of insert plate to be increased is proposed. Further, it is shown that it is much effective in reducing the stress concentration by adopting the optimized shape around discontinuous parts of ship structures even without using the insert plate.
