Topology Optimization

Definition

Topology optimization is a mathematical approach that optimally distributes material within a given design space to achieve maximum performance while minimizing weight and material usage. This technique is crucial for enhancing the structural efficiency of components in industries like automotive and aerospace, where weight reduction can lead to improved fuel efficiency and overall performance. It allows engineers to design parts that are tailored to specific loads and constraints, resulting in innovative shapes that traditional design methods may not achieve.
