Topology Optimization

Definition

Topology optimization is a mathematical method used to optimize the layout of material within a given design space, subject to constraints and loads, to achieve the best performance. This technique is crucial in the development of advanced materials and composites, as it allows engineers to create structures that maximize strength while minimizing weight, especially important in the harsh conditions of deep-sea environments.
