Soft topological modes protected by symmetry in rigid mechanical metamaterials
Soft topological modes protected by symmetry in rigid mechanical metamaterials
Topological mechanics can realize soft modes in mechanical metamaterials in which the number of degrees of freedom for particle motion is finely balanced by the constraints provided by interparticle interactions. However, solid objects are generally hyperstatic (or overconstrained). Here, we show how symmetries may be applied to generate topological soft …
