Collagen Cross-linking and Ultimate Tensile Strength in Dentin

Journal of Dental Research, 2004
Several studies have indicated differences in bond strength of dental materials to crown and root dentin. To investigate the potential differences in matrix properties between these locations, we analyzed upper root and crown dentin in human third molars for ultimate tensile strength and collagen biochemistry. In both locations, tensile strength tested

Ultimate tensile strength of fetal and adult human tendons

Journal of Biomechanics, 1970
Abstract Ultimate tensile strengths of human tendons were determined with an evaluation of the following criteria: adult or fetal; embalmed or unembalmed; from superior limb or inferior limb; and associated with extensor muscle or flexor muscle.

Ultimate tensile strength of five interchangeable prosthetic retaining screws

Implant Dentistry, 1996
Implant prosthetic retaining screws have been reported to serve as built-in safety factors to protect against overload in the implant's "vertical stack," although loosening and fracture of retaining screws are often considered complications. Manufacturers have responded by introducing interchangeable prosthetic retaining screws, which can give the ...

The yield and ultimate tensile strength of steel welds

Materials Science and Engineering: A, 1997
Abstract The design of welding alloys to match the ever advancing properties of newly developed steels is not an easy task. It is traditionally attained by experimental trial and error, modifying compositions and welding conditions until a satisfactory result is discovered.

Ideal and Ultimate Tensile Strength of a Solid Body

High Temperature, 2018
The mechanical stability of an ideal elastic solid under infinitesimal and finitesimal changes in its state parameters is considered. The temperature and density dependences of the isothermic moduli of bulk compression K, simple shear, and tetragonal shear in a Lennard-Jones face-centered cubic (FCC) crystal have been determined by means of molecular ...

Effect of Gamma Irradiation on Ultimate Tensile Strength of Enamel and Dentin

Journal of Dental Research, 2009
The effect of gamma irradiation therapy on the ultimate tensile strength (UTS) of enamel and dentin in relation to prism orientation, dentin tubule orientation, and location is unknown. It was hypothesized that tubule and prism orientation, location, and irradiation have an effect on the UTS of dental structures.

Application of crosslinkers to dentin collagen enhances the ultimate tensile strength

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2006
AbstractThe stabilization of dentin collagen with biocompatible crosslinking agents may be of clinical importance to improve dentin bond strength. The present study aimed to evaluate the effect of three collagen crosslinking agents on the ultimate tensile strength (UTS) of undemineralized and demineralized dentin.

Ultimate tensile strength of an artificial bulk superconductor with voids

Superconductor Science and Technology, 2006
Rare earth based bulk superconductors originally have many voids and cracks. Thus their ultimate tensile strengths are not material constants but apparent ones depending on the voids and cracks in each bulk. In this study, based on the observations of the surface of the actual specimens, artificial samples with voids were generated for numerical stress

Ultimate tensile strength of composites exhibiting fiber fragmentation

Composites Science and Technology, 1996
An estimate of the achievable longitudinal strength of fiber-reinforced composite systems is provided by models that are based on fiber fragmentation, interface sliding and global load sharing. A simple model is shown to provide a compact expression for the longitudinal strength and to closely approximate the values obtained from more detailed ...

The ultimate tensile strength of metal and ceramic-matrix composites

Acta Metallurgica et Materialia, 1993
The tensile strength of ceramic and metal matrix composites is subject to an important role of the fiber/matrix interface. The mechanical properties of this interface dictate the stress concentration that develops in fibers that surround a failed fiber. An analysis of this phenomenon is used to illustrate interface conditions that sufficiently diminish
