Deformation and Failure Mechanisms in Metallic Microlattice Structures Manufactured by Selective Laser Melting at Various Strain Rates

摘要：

　　New additive manufacturing technologies have recently advanced the development of microlattice structures with periodic unit cells, which are attractive in aerospace applications due to their light weight and good specific mechanical properties. In this work, selective laser melting was used to fabricate stainless steel microlattice structures. Mechanical behaviour in microlattice structures were characterised at different strain rates using various experimental techniques (such as split-Hopkinson pressure bars, Taylor impact, and ballistic gas gun impact).
