Description

Abstract: Topology optimization is a mathematical strategy enhancing a system's performance by figuring out the best arrangement of materials for a certain set of loads, boundary conditions, and constraints. In basic terms, it builds a design space from a model (3D model). To make the design more efficient, it then eliminates or displaces material inside it. By defining cavities in continuous design domains, topology optimization is an excellent technique for generating lightweight, high-performance, and cost-effective structures. Like every other optimization problem, it needs some boundary conditions, constraints, an objective function, and criteria to attain optimality, which must be decided by the type of design we are making, material costs, mechanical performance, and resistance to failure. Since there are several iterations in the optimization rounds which allow us to play with variables within the boundary conditions to come up with an aesthetically pleasing, mechanically optimized design. We are in hope that the proper implementation of this would lead to the betterment of society.
