Abstract

The Miura Ori auxetic geometry has been deeply studied for its capability to reach high negative Poisson coefficient values. This response is associated with some geometrical configuration, and there are several examples in specific literature. Miura Ori metamaterial has been analyzed with static loads, while from the dynamical side, the studies have been conducted with analytical/numerical techniques. The authors in this work would like to analyze this subject and propose an experimental setup (The most suitable technique appears to be an interferometric one, i.e., the Time-Averaged Speckle approach.) to get the modal response of a Miura Ori specimen. The results are validated by comparison with FEA simulation to state the reliability of experimental results.
