Mechanical strength of dental implants.
Journal of applied biomaterials & biomechanics : JABB, 2008A series of mechanical strength tests have been carried out in order to characterize some dental implants. Most specimens tested were of the tapered-joint kind, but for comparison further tests have been carried out on screw-joined implants. The loads applied were similar to those existing in the typical working conditions of the component; however, in

Mechanical Strength of Porcelain
Journal of the American Ceramic Society, 1957The mechanical strength of porcelain, in which a glassy phase is the major part, is shown to be influenced mainly by stresses set up in the glassy phase rather than by the amount or size of mullite crystals formed. A crystalbe material (quartz) having a coefficient of expansion higher than that of the glassy phase will establish favorable prestresses ...

Optimizing the Mechanical Strength of Adobe Bricks
Clays and Clay Minerals, 2009AbstractEcologic building materials such as adobe bricks have become of greater economic importance in recent years. In the present work, the addition of selected materials to improve the compressive and bending strengths of adobe bricks was tested. The raw material (loam UD) was analyzed for its mineralogical and chemical composition. The loam studied

Strength Mechanisms of Dental Solder Joints
Journal of Dental Research, 1974Derivations of the triaxial state of stress and relative strain rate within the solder agree with the types of strengthening found in soft lead-tin solder butt joints. But for the dental gold casting alloys and hard gold solders tested, joint strengths were only influenced by porosity and not by size or rate of testing.

Mechanical Strength of Microstructured Optical Fibers
Journal of Lightwave Technology, 2014An experimental study of the mechanical reliability of microstructured optical fibers (MOFs) is reported. Tensile tests were carried on five types of MOFs and two reference fibers, and the tensile strengths were analyzed using Weibull statistics. Optical microscopy of the surfaces of rupture allowed identifying the critical flaws and determining the ...

Mechanism of strength increase for a hydrothermal porcelain
Dental Materials, 2003The objectives of this study were to verify the formation of a hydrolyzed surface layer on Duceram LFC, to determine the effects of such a layer on mechanical material properties, and to identify a specific mechanism responsible for any strength increase observed.Specimens were fabricated from dentin porcelain by a vibration blotting technique and were

Strength and Strengthening Mechanisms
1984The strength of a material depends on various intrinsic and extrinsic factors. Although the most important is the chemical composition, the properties can be manipulated by altering the structure. Various mechanical, thermal, and surface treatments are used to create the desired balance of strength, hardness, and ductility.

Biocompatible microcapsules with enhanced mechanical strength
Journal of Biomedical Materials Research, 2001AbstractA block copolymer, (short‐chain alginate)‐co‐MPEG, was synthesized and used for coating the capsular membranes of the photosensitive microcapsules. The resulted microcapsules exhibited an excellent mechanical strength. The permeability test results revealed that the capsular membrane was freely permeable to cytochrome C and myoglobin, less ...

The Mechanical Strength of Various Suture Techniques
Journal of Hand Surgery, 1992The mechanical strengths of five techniques of tendon repair have been evaluated using human cadaver tendons. A modified Kessler repair with a peripheral circumferential suture and the method of Becker were found to require the greatest load to produce gapping, but the Becker and Savage repairs withstood the highest load before failure.

The Characterization of the Mechanical Strength of Chewable Tablets
Pharmaceutical Development and Technology, 1998The purpose of this research was to identify possible test procedures for the evaluation of the strength of chewable tablets with respect to prevention of damage to teeth or mandibular joints when tablets are consumed. Diametral compression and flexure tests were employed to evaluate the strength of commercial samples from five manufacturers of ...
