| Abstract Scope |
The manufacturing of complex lattice structures is made possible through additive manufacturing. Among the different possible lattice topologies, plate lattices have attracted attention for ballistic impact applications because of their potential for high energy absorption at low relative weights. Here, we manufacture and study different plate lattice topologies in three different mechanical tests: quasi-static compression, Split Hopkinson Pressure Bar dynamic compression, and ballistic impact. Plate lattice samples were manufactured using laser powder bed fusion, where plate lattice topology and volume fraction were varied. Stress-strain behaviors were extracted from compression testing and specific energy absorptions were calculated. Specific energy absorptions and ballistic penetration resistances were compared to determine the effect of plate lattice topology and volume fraction. Finite element simulations of the mechanical tests were also performed and compared to experimental test results. |
