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.

Effects and Mechanisms of Strength Training in Children

International Journal of Sports Medicine, 2011
It has been demonstrated that strength training can be organized in children in a safe and effective way. However, there is limited data regarding its impact on muscle hypertrophy. This study investigated the effects of a high-intensity strength training (HIS) on knee extensor/flexor strength, countermovement (CMJ) jumping height, postural control ...

Determination of the Mechanical Strength of Microcapsules

2016
The promise of pancreatic islet transplantation is hindered by organ shortage, and the need for immunosuppression of transplant recipient in order to prevent rejection. Alginate microencapsulation can overcome these hurdles; however further optimization of this technique is required.

The mechanical and strength properties of diamond

Reports on Progress in Physics, 2012
Diamond is an exciting material with many outstanding properties; see, for example Field J E (ed) 1979 The Properties of Diamond (London: Academic) and Field J E (ed) 1992 The Properties of Natural and Synthetic Diamond (London: Academic). It is pre-eminent as a gemstone, an industrial tool and as a material for solid state research.

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 ...

Mechanical strength of dental implants.

Journal of applied biomaterials & biomechanics : JABB, 2008
A 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

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.

Optimizing the Mechanical Strength of Adobe Bricks

Clays and Clay Minerals, 2009
AbstractEcologic 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
