Collagen Cross-linking and Ultimate Tensile Strength in Dentin
Journal of Dental Research, 2004Several 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.

The yield and ultimate tensile strength of steel welds
Materials Science and Engineering: A, 1997Abstract 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.

The ultimate tensile strength of metal and ceramic-matrix composites
Acta Metallurgica et Materialia, 1993The 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

Ultimate tensile strength of an artificial bulk superconductor with voids
Superconductor Science and Technology, 2006Rare 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, 1996An 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 ...

Effect of Gamma Irradiation on Ultimate Tensile Strength of Enamel and Dentin
Journal of Dental Research, 2009The 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, 2006AbstractThe 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.

Fatigue strength dependence on the ultimate tensile strength and hardness in magnesium alloys
International Journal of Fatigue, 2015Abstract The relationships between fatigue strength and ultimate tensile strength as well as hardness have been studied in high-strength NZK alloys (Mg– y Nd– z Zn– x Zr) and other magnesium alloys. In the absence of casting defects, clear linear relationships have been found between the fatigue strength and the ultimate tensile strength and the ...

Tensile properties of the annulus fibrosus
European Spine Journal, 1993Part I of this study showed that collagen fibres do need not need to be continuous to reinforce the annulus fibrosus, and that 15-mm-wide samples of annulus retain about 44% of their in situ stiffness and strength when stretched vertically. Part II investigated the ultimate tensile strength (UTS) and fatigue life of such samples.

Effect of the Association of Nystatin with a Tissue Conditioner on its Ultimate Tensile Strength
Journal of Prosthodontics, 2006Purpose: This study evaluated the ultimate tensile strength of a tissue conditioner without nystatin incorporation (GI—control group) and the same tissue conditioner modified by the addition of nystatin in two concentrations: GII—500,000 International Units (U) and GIII—1,000,000 U, in which each milligram of the medicament corresponded ...
