Abstract Scope |
Since the emergence of advanced manufacturing technologies like additive manufacturing, fabrication of complex microlattice structure has become possible. The high energy absorbing capabilities and higher strength to weight ratio of the microlattice has contributed to its wide range application in lightweight and high-energy absorbing structures. With relative density being the most important factor for the mechanical characteristics of microlattice, the geometry of the microlattice unit cell also contributes significantly toward the deformation behavior of the microlattice. In this study, the mechanical performance of metallic tetrahedral microlattice structures, which have not been previously studied, is investigated over a range of relative densities and strut diameters. The quasi-static compression test results have been validated using finite element analysis. The energy absorption capabilities and deformation behavior of the different microlattice structures are explored. The analysis also establishes better mechanical behavior of tetrahedral microlattice structures as compared to BCC microlattice. |
