TESTS OF BRIQUETTES FOR MECHANICAL STRENGTH

Metallurg, 2021
The expediency of applying the test methods for sinter and pellets to determine the mechanical strength of blast-furnace briquettes is considered. Based on numerical modeling, the behaviors of pellets and briquettes under shock and abrasive loads in a rotating drum, static compressive loads, and when dropped from a height are compared. It is shown that

Mechanical Strength of Scaphoid Fixation

Journal of Hand Surgery, 1996
We have investigated five devices suitable for scaphoid fixation (ASIF 2.7 mm and 3.5 mm cannulated screws, Herbert, Herbert-Whipple, and Howmedica Universal Compression Screw). The biomechanical properties tested were compression and resistance to cantilever bending.

Mechanical Strength of Microstructured Optical Fibers

Journal of Lightwave Technology, 2014
An 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 ...

Biocompatible microcapsules with enhanced mechanical strength

Journal of Biomedical Materials Research, 2001
AbstractA 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 ...

Strength Mechanisms of Dental Solder Joints

Journal of Dental Research, 1974
Derivations 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 Porcelain

Journal of the American Ceramic Society, 1957
The 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 ...
