The fracture resistance of dental materials

Journal of Oral Rehabilitation, 1995
summary A novel test procedure was developed that provides the basis for a standard plain strain fracture toughness test to evaluate fracture resistance of resin‐based materials. This procedure utilizes a notched disc specimen. Using this technique, a new concept of‘Torque to initiate fracture (T)’was suggested.

On the fracture resistance of dragonfly wings

Journal of the Mechanical Behavior of Biomedical Materials, 2019
The biological success of insects is attributed to evolution of their wings. Over 400 million years of evolution, insect wings have become one of the most complex and adaptive locomotor structures in the animal kingdom. Although seemingly fragile, they satisfactorily perform their intended function under millions of cycles of repeated stress without ...

Reduction in Fracture Resistance of the Root with Aging

Journal of Endodontics, 2017
The incidence of vertical root fracture in endodontically treated teeth increases with patient age. This study evaluated the microstructure, chemical composition, and mechanical properties of radicular dentin as a function of aging.Single-rooted teeth were obtained from adult donors ranging from age 15 to older than 80 years.

Fracture resistance of paper

Journal of Materials Science, 1974
An attempt has been made to apply the concepts of fracture mechanics to describe the behaviour of a paper sheet with a crack. Considering paper as an orthotropic homogeneous continuum, the critical strain energy release rate, G c, for eight different papers has been measured using linear elastic fracture mechanics. Also, a direct measurement of work of

Resistance of Hardmetals to Fracture

Powder Metallurgy, 1998
Abstract Strength of WC and TiC base hardmetals and their durability in metalforming (blanking) operations have been investigated. It has been shown that transverse rupture strength R TZ, critical stress intensity factor K Ic, and ultimate plastic strain ep as individual properties do not enable exact estimation of the resistance of hardmetals to ...

Microstructure and the resistance of rock to tensile fracture

Journal of Geophysical Research: Solid Earth, 1985
The resistance of rock to tensile fracture may be measured by its fracture energy GI, which is found to range from 40 to 200 J/m2 in tests on nine types of sedimentary and crystalline rock. Differences in microstructure among the rocks tested are the principal cause of differences in the steady state value of GI, in the distance that a crack must ...
