On the fracture toughness of equine metacarpi

Journal of Biomechanics, 1979
Abstract This paper reports on the measurement of both tensile and fracture behavior of paired equine metacarpi. Tests were performed at strain rates of 10 −4 sec −1 . Three-point bending tests were carried out on notched specimens to attain the toughness values and the same specimens were used to obtain the elastic moduli.

Fracture Toughness of Human Enamel

Journal of Dental Research, 1981
A microindentation technique was employed to estimate the fracture toughness of human enamel. A pattern of increasing fracture toughness values existed from incisal to cervical in incisor enamel. Statistical analysis indicated that the molar enamel was more brittle than either the canine or incisor enamel. It was observed that the cracks emanating from

Analysis of fracture toughness data

Lifetime Data Analysis, 1995
In studies of the fracture toughness of irradiated weld metal, specimens are subjected to an increasing load. The test on any one specimen might be terminated by choice or because the specimen ruptures. Prior to termination, ductile tearing might or might not have occurred. The situation is thus basically one of competing risks, with different types of

The fracture toughness of cancellous bone

Journal of Biomechanics, 2006
The mechanical capacity and integrity of cancellous bone is crucial in osteoporosis, a condition which is set to become more prevalent with increasing lifespan and population sizes. The fracture toughness (FT) of cancellous bone has never been examined before and the conditions associated with the growth of a major crack through the lattice of ...

Fracture toughness of dental amalgams

Biomaterials, 1983
The fracture toughness of selected low and high copper content amalgams has been determined using three testing methods. A miniature single edge notched three point bend specimen, based on BS 5447, was found to give the most reliable values of fracture toughness, determined both as the work of fracture and as the opening mode plane strain critical ...

Fracture toughness of human dentin

Journal of Biomedical Materials Research Part A, 2003
AbstractThe purpose of this study was to determine the fracture toughness (KIC) of human dentin and to test the null hypothesis that KIC is not affected by the orientation of dentinal tubules relative to the plane of crack propagation. Triangular prisms (4 × 4 × 4 × 8 mm) were obtained from human molars and tested using the notchless triangular prism ...
