With a density based method, volume minimization has been achieved. All processes have been realized with the help of finite element method implemented in a commercial software. A standard lifting hook model has been used in the process. After optimization, the standard lifting hook was remodeled with CAD software. Then the new model was analyzed. This process has been repeated for three different models. On the basis of the obtained results, the topology optimization undertaken within the scope of the study demonstrates that it is possible to redesign a lifting hook with reduced weight and at the same time to satisfy the required strength properties. © 2021 The Authors.

Introduction Engineering is a set of research and development processes including design, analysis and production. In many of these processes, there are certain challenges that need to be tackled. These problems can be different from each other in some aspects. There are also many engineering tools that solve specific problems encountered and improve their results. The utilization of topology optimization methods is one of these tools, which helps engineers to achieve some engineering objectives on specific problems [Arora (2017)]. One of the problem areas in which topology modification is used is weight reduction in mechanical designs.
