Detailed meso-scale simulations of the transient deformation in additively manufactured 316 L stainless steel lattices characterized by phase contrast imaging

Shock compression behavior of stainless steel 316L octet-truss lattice structures

“…The difference in fit values between experimental displacements and constant velocities was small (1-2% for S, 10-20% for m f it , and 2% for m crush ) and . Higher values were observed for all quantities in simulations which may be dependent on geometric defects and distributions [26].…”

“…Hawreliak et al [14] and Lind et al [15] have conducted experiments on sub-millimeter UC polymeric materials which clearly show a two-wave structure of an elastic precursor wave followed by compaction shock wave. Branch et al [26] conducted experiments on stainless steel 316L lattices (2x2x3 UC) using phase contrast imaging and demonstrated significant effects of experimental geometries on the shock response. On a smaller scale, Portela et al [27] investigated impact behavior of nano-scale brittle lattice structures which showed a compaction shock response with distinct regions of intact and densified material.…”
