Abstract Scope |
Additive Manufacturing (AM) has transformed part design, making it possible to create intricate geometries that traditional manufacturing techniques cannot. Mechanical Homogenization (MH) offers a faster approach to explore the average mechanical characteristics of prescribed topologies. However, MH can have poor correspondence when scaled to complex parts. To overcome this limitation, we propose a homogenization-based topology-optimization (TO) approach to produce optimized topologies using MH while satisfying part-level constraints. Our MH model captures different deformation regimes, from linear elastic to plateau and densification regimes that are the result of buckling and self-contact of individual struts. Incorporating such constraints in classical TO approaches is nearly impossible. We demonstrate the effectiveness of our approach through an insole optimization problem. By incorporating homogenization into the TO process, we aim to make the design process more efficient and accessible to a wider range of users. |
