== Abstract ==

In this study, we performed the density-based topology optimization in static problem using our modified optimality criteria method. In topology optimization based on the homogenization or density methods, the optimality criteria (OC) method is often employed as update equation for design variables. But the OC method needs to set the weighting factor and move limit. In the modified OC method, they are not necessary. However, in the international paper we have already reported, the performance function did not always go down in 3-dimensional static problems, thus we discuss the updating process in detail in this study. As a result, we confirmed that even the OC method was employed, the performance function increased significantly during the update process. The increase in the performance function when using the modified OC method is more supressed than when using the OC method. 1. Introduction In recent years, the structual optimization theory has been used to improve the performance of various products with the improvement of computatioanl performance and manufacturing technology
