Fig. 2: Finite element analyses of cubic+octet plate-lattice performance show that face-holes produce only a minimal knockdown effect and do not contribute strongly to anisotropy.
From: Plate-nanolattices at the theoretical limit of stiffness and strength
Effective Young’s modulus (E) normalized by the constituent material’s Young’s modulus (Es) (a) and Zener anisotropy ratio (a), (b), with and without holes, the dashed lines are the Hashin-Shtrikman (HS) upper bound. Simulated models of 40% relative density (c, d) show that holes do not significantly change the strain energy distribution (Uε), here normalized by the average strain energy (\(\bar U_\varepsilon\)), while introducing local stress concentrations.
