Abstract:
Hierarchical materials consist of microstructural elements which have themselves internal structure, forming a self-similar pattern on multiple scales [1]. Such materials are ubiquitous in biological materials [2] such as collagen [3], bone [4], and wood [2]. We analyse the process of damage accumulation and global failure in hierarchically patterned materials, and compare them with non-hierarchical reference patterns.
The nucleation and propagation of crack in uniaxially loaded materials with statistically distributed local failure thresholds is studied using a beam lattice model [1, 5].
We show that hierarchical material failure is characterized by diffuse local damage nucleation that eventually spreads throughout the network. Nonhierarchical materials, on the other hand, fail in a sequence of damage nucleation, crack formation, and stress-driven crack propagation.
