The influence of strut waviness on the tensile response of lattice materials

Recent advances in additive manufacturing methods make it possible, for the first time, to manufacture complex micro-architectured solids that achieve desired stress versus strain re- sponses. Here, we report experimental measurements and associated finite element (FE) calcu- lations on the effect of strut shape upon the tensile response of two-dimensional (2D) lattices made from low-carbon steel sheets. Two lattice topologies are considered:...
