Abstract
In this research, we study the topological effect in both 1D and 2D metastructures consisting of chiral-shape prismatic tensegrity units. The unique axial-torsional motion introduces coupled local resonance which produces the needed Dirac degeneracy for the topological states at low frequency. A multi-resonantor design is also proposed for additional Dirac cones which can be opened for mutiple non-trivial bandgaps. Further research shows that topological phase transition can be also achieved through the adjustment of chirality. Finally, prestress control on the topological interface states is studied in both 1D and 2D cases.
