Quasi-static uniaxial loading and loading of elasto-magnetic metamaterials with Q=1, w0=0.14L0, and a0=0.17b0. A local configuration transitions from closed to open phase emerges at the top and bottom end. It propagates toward the sample’s center—the configuration changes to a homogeneous open phase as the deformation increases in the loading cycle. The sample maintains the open phase in the unloading path, ending with a fast transition to the closed phase as the magnets snap to each other within a small distance.
