Cracking Down on Fracture to Functionalize Damage

Year: 2025

Type: article

Abstract: In this Letter we propose a novel relationship between topology and damage propagation in Maxwell lattices that redefines fracture as a functional design feature rather than mere degradation. We demonstrate that topologically protected modes, inherently robust against perturbations, localize along lattice discontinuities and govern the mechanical response. By precisely engineering the microstructure, we direct these modes to control stress distributions and trigger predictable, controlled damage. Our findings, validated through comprehensive numerical simulations and experiments, advance our understanding of nontrivial mechanical responses in Maxwell lattices and establish a clear framework for designing materials with improved fracture energy. This Letter paves the way for further exploration of topology-driven phenomena in mechanical systems and promises a new direction in the design of robust materials.
