Ultimate tensile strength of tooth structures

Dental Materials, 2004
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.Intact occlusal enamel surfaces from extracted human third molars were etched with 37% phosphoric acid and ...

Analysis of tensile test beyond the ultimate tensile strength

Journal of Materials Processing Technology, 1992
Abstract The strain of tensile test specimens in the domain beyond their ultimate tensile strength was analysed by means of a tensile test machine supplemented by a television camera and computer. The work served to verify the feasibility of computing the strain parameters by a routine where the inputs are only data describing the force versus ...

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 ...

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.

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.

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 ...

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 ...

An estimate of the ultimate tensile strength of water

Journal of Physics D: Applied Physics, 1976
An estimate is made of the ultimate tensile strength of water with data from previously reported isochores obtained using the Berthelot tube method. The agreement with the theoretical values predicted by Temperley's theory (1947) is most satisfactory.
