- Topology optimization using sensitivity filtering based on equivalent stress
説明
In this study, we propose a sensitivity filtering method based on equivalent stress in topology optimization analysis. It is necessary to apply the sensitivity filtering technique to obtain the optimal structure topology without checkerboard pattern. In general, the filtering radius is given as constant value in the topology optimization, and an optimal structure topology with gray scale is sometimes obtained. Therefore, in this study, we focus on the difference of equivalent stress distribution in case of each optimal structure topology, and propose a filtering radius adjustment method based on the value of equivalent stress in each structure element. A cantilever beam model is introduced as a numerical example, and some numerical results are shown in this paper.
