| Abstract Scope |
Manufacturing of Innovative design of optimized structures such as lattices were made possible in the past decades by advanced technics such as additive manufacturing. One of the important barriers in creation of such lattices are the manufacturability complications and lack of understanding of their mechanical behaviour. Additively manufactured lattices are exploited in a wide range of multifunctional applications, such as energy absorbers, vibration and sound control devices, lightweight structural panels, and biomedical applications. In this research we aimed to design, manufacture, and analyse lattices for energy absorption applications. We have experimentally and numerically investigated the mechanical properties of filled and unfilled 3D printed polymer lattices to obtain highest energy absorption capacity per unit density under impact loading. Furthermore, effect of a soft polymer filling material on behavior of these lattices is investigated. Machine Learning is used to design optimum multimaterial lattice for high energy absorption under impact loading are identified. |
