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…
