Constant force amplifies pulse solitons via polarization coupling in mechanical metamaterials
Zehuan Tang, Yuanwen Gao
Unlike kink solitons with nonzero topological charge, pulse solitons cannot be driven by the experimentally most easily implemented constant force because of their zero topological…
Bifurcation of the quasi-stationary velocity of strongly discrete transition waves driven by gravity
Zehuan Tang, Qing Xia, Hui Chen +2
Transition waves are common in multistable mechanical metamaterials, and the dynamics of weakly discrete transition waves under driving forces have been extensively discussed. Howe…
Evolution of static to dynamic mechanical behavior in topological nonreciprocal robotic metamaterials
Zehuan Tang, Tingfeng Ma, Hui Chen +1
Based on the Maxwell-Beatty reciprocity theorem, static non-reciprocity has been realized by using nonlinearity, but this non-reciprocity has strict restrictions on input amplitude…
Anomalous size effects with fixed criticality in bistable flexible mechanical metamaterials
Zehuan Tang, Tingfeng Ma, Boyue Su +3
When the structure deformation is dominated by the low-energy deformation mode, the structure hardens with the increase in the size (number of units) at small sizes. This anomalous…
