Stress control in non-ideal topological Maxwell lattices via geometry
Harry Liu, Siddhartha Sarkar, A. Nafis Arafat +3
Topological mechanical metamaterials have demonstrated exotic and robust mechanical properties which led to promising engineering applications. One of such properties is the focusi…
Robustness of stress focusing in soft lattices under topology-switching deformation
Caleb Widstrand, Xiaoming Mao, Stefano Gonella
Recent developments in topological mechanics have demonstrated the ability of Maxwell lattices to effectively focus stress along domain walls between differently polarized domains.…
Omnimodal topological polarization of bilayer networks: analysis in the Maxwell limit and experiments on a 3D-printed prototype
Mohammad Charara, James McInerney, Kai Sun +2
Periodic networks on the verge of mechanical instability, called Maxwell lattices, are known to exhibit zero-frequency modes localized to their boundaries. Topologically polarized…
Switchable phonon diodes using nonlinear topological Maxwell lattices
Di Zhou, Jihong Ma, Kai Sun +2
Recent progress in topological mechanics have revealed a family of Maxwell lattices that exhibit topologically protected floppy edge modes. These modes lead to a strongly asymmetri…
Wave control through soft microstructural curling: bandgap shifting, reconfigurable anisotropy and switchable chirality
Paolo Celli, Stefano Gonella, Vahid Tajeddini +3
In this work, we discuss and numerically validate a strategy to attain reversible macroscopic changes in the wave propagation characteristics of cellular metamaterials with soft mi…
