Bioinspired Design Criteria for Damage‐Resistant Materials with Periodically Varying Microstructure
Many biological materials, such as bone, nacre, or certain deep-sea glass sponges, have a hierarchical structure that makes them stiff, tough, and damage tolerant. Different structural featuresExpand

Improvements of strength and fracture resistance by spatial material property variations
Abstract A material with spatial variation in the elastic modulus E can have a much higher apparent fracture resistance and fracture stress than a comparable homogeneous material. The effect occursExpand
