Nanofibril-mediated fracture resistance of bone [PDF]

Bioinspiration & Biomimetics, 2021
Abstract Natural hard composites like human bone possess a combination of strength and toughness that exceeds that of their constituents and of many engineered composites. This augmentation is attributed to their complex hierarchical structure, spanning multiple length scales; in bone, characteristic dimensions range from nanoscale ...

Fracture Resistance of Ceramics: Edge Fracture Method [PDF]

Strength of Materials, 2005
Fracture resistance of macrohomogeneous linear elastic yttria, scandia, alumina, zirconia, and silicon nitride ceramics was studied upon flaking of the edges of rectangular specimens with the Rockwell indenter. The correlation between the obtained estimates and fracture toughness test results gained by the single-edge V-notched beam method was ...
