Fracture Toughness and Fatigue Threshold of Tough Hydrogels
ACS Macro Letters, 2018Hydrogels of numerous chemical compositions have achieved high fracture toughness on the basis of one physical principle. As a crack advances in such a hydrogel, a polymer network of strong bonds ruptures at the front of the crack and elicits energy dissipation in the bulk of the hydrogel.

The fracture toughness of dental composites
Journal of Oral Rehabilitation, 1982SummaryThe development of the stress intensification factor (KIC) and the fracture strength (σF) have been determined for a range of composite products. Changes in KIC resulting from storage are equated to the progression of polymerization and the loss or gain of plasticizer.

Fracture toughness of thin and tough plates
International Journal of Fracture, 1978Abstract : Wells has proposed using crack tip opening displacement as a measure of the fracture toughness of cracked plates in general yielding. The concept is applicable to thin plates loaded to extensive plastic deformation. The method is used to determine the fracture toughnesses of HY-80 steel plates. (Author)

Fracture Toughness of Human Dentin
Journal of Dental Research, 1986Plane strain fracture toughness (K IC ) was determined for coronal dentin using compact tension test-pieces obtained from recently extracted permanent lower molar teeth. Specimens were prepared and tested such that the moving crack front was aligned parallel to the tubule orientation.

Fracture toughness of compact bone
Journal of Biomechanics, 1976The tensile fracture stress (σfr) of longitudinal bovine tibia compact bone specimens was measured as a function of the length (c) and radius of curvature (r) of machined edge cracks. It was established that, for a given value of r, then σFr = Ac −12 − B where A and B are constants.

Fracture toughness of frozen meat
Meat Science, 1987The fracture toughness and dynamic mechanical moduli of frozen beef M. semitendinosus were investigated at various sub-zero temperatures using several different test geometries. Traditional fracture mechanics methods were considered inapplicable to frozen meat, since considerable plastic flow occurs in addition to elastic deformation and fracture ...

The fracture toughness of repaired composite
Journal of Oral Rehabilitation, 1986SummaryThe fracture toughness (K′IC) at the interface formed between a composite substrate and more recently placed composite has been measured to determine the strength of the repair. The substrate material was 24 h old at the time of the repair and the fracture toughness of the repair was measured 24 h later. Five composite products were selected for

Fracture toughness and hydraulic fracturing
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989Abstract A study of the influence of fracture toughness on the shape of a hydraulically induced fracture is presented. Three-dimensional numerical simulations of fracture propagation show that fracture toughness is not the main controlling parameter if one chooses fracture toughness values determined at ambient conditions.
