Optimization of the small-amplitude dynamic triggering mechanism of bi-stable metamaterials

We analyze and optimize a new class of multi-stable mechanical metamaterials with a high stretch ratio between the contracted state and the expanded state. The goal is to maintain mechanical stability in two or more configurations while achieving controlled reconfiguration. The designed architected materials can switch between different stable states under mechanical stimuli without the loss of structural integrity. Furthermore, we also optimize the small-amplitude dynamic triggering mechanism for state-switching to enable a broad range of applications.
