#13761, On the Miura Ori Modal Response: A Look Throughout the Experimental Side

The Miura Ori geometry is a particular origami technique that has been studied for its auxetic properties, i.e., for its capability to reach high negative Poisson coefficient values. Auxetic metamaterials are known to lead to enhanced fracture toughness, impact protection and undergo to synclastic curvature instead of anticlastic one.
From the experimental viewpoint, Miura Ori metamaterial has been analyzed in relation to static loads, while the dynamical properties are often estimated using analytical/numerical techniques.
The authors in this work would like to experimentally study the modal response of Miura Ori specimens using the speckle interferometry technique. The validation of the results is obtained by a comparing with FEA simulation, which consents to state the reliability of the experimental results.
