Tensile strength of dentin after bleaching treatment.
The mechanical properties of dentin are changed after bleaching, although the effects of the bleaching conditions on the tensile strength of dentin have not been determined. In the current study, a tensile test of bovine dentin was conducted after bleaching and the effects of the bleaching conditions were investigated, including the number of bleaching times, the location where the bleaching ag...
متن کاملTensile Strength of the Eggshell Membranes
STRNKOVÁ JANA, NEDOMOVÁ ŠÁRKA, KUMBÁR VOJTĚCH, TRNKA JAN. 2016. Tensile Strength of the Eggshell Membranes. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 159–164. The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from diff erent bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the m...
متن کاملUltimate tensile strength of tooth structures.
OBJECTIVE This study determined the ultimate tensile strength (UTS) of enamel (E), dentin (D) and dentin-enamel junction (DEJ) using the microtensile technique. It was hypothesized that the UTS of dental structures varies according to location and nature. METHODS Intact occlusal enamel surfaces from extracted human third molars were etched with 37% phosphoric acid and bonded with a one-bottle...
متن کاملIsotropic tensile strength of molecular glasses
The relationship between the bulk density and pressure of configurations corresponding to local minima on the potential energy surface of molecular models of ethane, n-pentane, and cyclopentane ~the equation of state of their energy landscape! has been explored. Like simpler, atomic fluids, these systems exhibit a limiting bulk density below which minimum energy configurations are no longer spa...
متن کاملTime-dependent strength of colloidal gels.
Colloidal silica gels are shown to stiffen with time, as demonstrated by both dynamic light scattering and bulk rheological measurements. Their elastic moduli increase as a power law with time, independent of particle volume fraction; however, static light scattering indicates that there are no large-scale structural changes. We propose that increases in local elasticity arising from bonding be...
