The relationships between tensile strength, mode I and mode II fracture toughness of rock: An empirical and microcracking perspective [PDF]
HeliyonThe 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.

Fracture Diodes: Directional Asymmetry of Fracture Toughness [PDF]
Physical Review Letters, 2021 Toughness describes the ability of a material to resist fracture or crack propagation. It is demonstrated here that fracture toughness of a material can be asymmetric, i.e., the resistance of a medium to a crack propagating from right to left can be significantly different from that to a crack propagating from left to right.

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

Fracture toughness of graphene [PDF]
Nature Communications, 2014 Perfect graphene is believed to be the strongest material. However, the useful strength of large-area graphene with engineering relevance is usually determined by its fracture toughness, rather than the intrinsic strength that governs a uniform breaking of atomic bonds in perfect graphene.

Stress Triaxial Constraint and Fracture Toughness Properties of X90 Pipeline Steel
Metals, 2022 The X90 pipeline steel with high-strength and high-toughness become the most popular pipeline steel. Due to the stress triaxial constraint and fracture toughness properties are the key factors for the stable work of pipeline steel, the research on the ...

The fracture toughness of inorganic glasses [PDF]
Journal of the American Ceramic Society, 2017 AbstractMeasuring the fracture toughness (KIc) of glasses still remains a difficult task, raising experimental and theoretical problems as well. The available methods to estimate KIc are reviewed, with emphasis on their respective advantages and drawbacks. In view of our current understanding, this analysis gives precedence to the SEPB method.
