Abstract
This thesis explores the mechanical behaviour of lattice structures and laser powder bed fusion(LPBF) metal alloys under quasi-static and dynamic loading. It investigates energy absorption ofisotropic topology-optimized lattice structures and the rate-dependent behavior of LPBFed alloys(CPTi, AlSi10Mg, and 316L stainless steel). The findings demonstrate the isotropy of the topologyoptimizedlattice and the strain rate sensitivity of LPBFed alloys. Additionally, the study explores therate-dependent response of a topology-optimized unit cell with different materials. Overall, thisresearch provides insights into the potential of these materials in engineering applications and offersimplications for light alloy implementation in impact applications.
