Abstract
Plate-based lattices have emerged as promising candidates for lightweight structural and
energy-absorbing applications; however, the latter remain largely underexplored. This study
investigatesthe quasi-static and dynamic compressive behaviour of BCC and FCC plate lattices
featuring a novel sinusoidal plate geometry. Lattices were additively manufactured in ABS and
tested across strain rates from 0.001 to 43.5 s⁻¹. The sinusoidal geometry promoted stable
deformation by suppressing localised failure in both plate lattices, albeit with reduced stiffness
and strength. Compared to BCC, sinusoidal FCC lattices exhibited pronounced strain-rate
strengthening, likely owing to the increased strain-rate sensitivity of bulk ABS under shear
loading. A Cowper–Symonds plasticity model provided robust dynamic strength predictions
across strain rates. These findings underscore the potential of sinusoidal plate lattices for
tailored energy absorption and deformation control in additively manufactured structures.
