Abstract

Manufacturing industries are aiming to reduce weight of the products at uncompromised structural performance. Topology optimization is a reliable technique to achieve the improved topologies at minimum material utilization. Nature is known as best manufacturer to bring complex structures with the existed materials. The present research is aimed to identify the constructal design patterns that existed in nature through topology optimization. Structures with different boundary conditions are modeled and optimized using Solid Isotropic Material Penalization (SIMP) method through ANSYS software under structural and thermal loading conditions. The performed case studies revealed that the optimized topologies are very close to the nature inspired patterns.
