The fracture toughness of eggshell [PDF]

Acta Biomaterialia, 2016
The shells of avian eggs are very brittle, but how brittle? Fracture toughness, Kc is a standard measure used widely to characterise engineering materials. We devised a novel way to measure Kc and applied it to commercial hens' eggs, obtaining a value of 0.3MPa√m. This value is much lower than previous published values, which we argue are incorrect and

Research on the influence of rock fracture toughness of layered formations on the hydraulic fracture propagation at the initial stage

Geohazard Mechanics
Deep underground rocks exhibit significant layered heterogeneity due to geological evolution and sedimentation. Rock fracture toughness, as one of the important indicators of hydraulic crack propagation, also exhibits heterogeneous distribution. In order

The relationships between tensile strength, mode I and mode II fracture toughness of rock: An empirical and microcracking perspective

Heliyon
The empirical relationships between tensile strength, mode I and mode II fracture toughness obtained by previous studies have the problem of a small amount of data for fitting, and more data are needed for further study.

Effects of Silicon on Mechanical Properties and Fracture Toughness of Heavy-Section Ductile Cast Iron

Metals, 2015
The effects of silicon (Si) on the mechanical properties and fracture toughness of heavy-section ductile cast iron were investigated to develop material for spent-nuclear-fuel containers. Two castings with different Si contents of 1.78 wt.% and 2.74 wt.%
