Behavior of auxetic structures under compression and impact forces (2017, methodology): “The work of Ruzzene et al and Scarpa et al is highly commendable in this regard [24, 25].”
In-plane elasticity of a novel auxetic honeycomb design (2017, background): “A variety of honeycomb configurations achieving positive/negative/zero Poisson’s ratio have been proposed and investigated with special focus on the in-plane mechanics, flatwise compressive strength and the transverse shear modulus [9-25].”
Flexible Skins for Morphing Aircraft Using Cellular Honeycomb Cores (2010, background): “Although some figures provided in this article are available in the literature (Gibson and Ashby, 1997; Scarpa et al., 2000), they are presented here to examine how variations in cell geometric parameters would simultaneously affect the in-plane stiffnesses, outof-plane deflections, and the maximum…”
A novel centresymmetric honeycomb composite structure (2005, methodology): “For increasing cell wall aspect ratios a, both the in-plane Poisson s ratio m12 and the Young s modulus ratio decrease, while the limiting internal cell angle h augments accordingly with the a sin(a/2) rule [3].”
