Soft topological lattice wheels

We investigate the large deformation and extreme load-management capabilities of a soft topologically polarized kagome lattice mapped to cylindrical domain through problem wheel rolling on an irregular surface. test surface–lattice interaction experimentally by subjecting 3D-printed topological prototype localized distributed boundary loads. This investigation reveals dichotomy in force transfer between two loading scenarios, whereby loads are absorbed with limited stress penetration into bulk small axle, compared Through numerical simulations, we compare against baseline solid highlight unique management opportunities offered configuration. These findings promote design objects enabled mechanics, which surplus softness, activated local asperities, can coexist globally stiff response that ensures satisfactory load-bearing capabilities.
