Computational Design of Architected Materials with Multifunctionality

Architected materials are engineered structures that possess intricate geometric designs achievable by emerging advanced manufacturing techniques like 3D printing, and recently gained significant attention in aerospace, automotive, naval, and medical applications due to their porous, lightweight properties and exceptional stiffness-to-weight and strength-to-weight ratios. Most of these applications require architected material to work as a multifunctional structure that can serve two or more purposes at the same time. For instance, bone tissue engineering application of an architected material where it serves as a scaffold requires the scaffold to provide mechanical support to the bone and at the same time facilitate tissue growth, or a load-carrying application of an architected material that requires the structure to be as lightweight as possible yet to show non-deformable properties under compressive and shear load. These multifunctional properties become challenging to achieve and require the intervention of computational design techniques for solutions. The current research works towards enhancing design flexibility and design optimization of architected materials for multifunctional purposes. This is achieved through the exploration of novel design strategies integrated with simulations to achieve their mechanical and mechanobiological performance followed by comprehensive bulk or heuristic evaluations to gain insight into property-tailoring. The results offer valuable insights into previously unexplored design spaces for multi-functional architected materials.
