Experimental realization of tunable Poisson's ratio in deployable origami metamaterials

D Misseroni, PP Pratapa, K Liu, GH Paulino - Extreme Mechanics Letters, 2022 - Elsevier
Origami metamaterials are known to display highly tunable Poisson's ratio depending on
their folded state. Most studies on the Poisson effects in deployable origami tessellations are
restricted to theory and simulation. Experimental realization of the desired Poisson effects in
origami metamaterials requires special attention to the boundary conditions to enable
nonlinear deformations that give rise to tunability. In this work, we present a novel
experimental setup suitable to study the Poisson effects in 2D origami tessellations that …
