Rim Thickness Factor to Evaluate Fracture Resistance of Spur Gears

open access: yesRevista Cubana de Ingeniería, 2011
In thin rimmed gears running with sufficient bending stress resistance at the tooth-root, fatigue cracks with propagation through the rims, rather than at the tooth fillet, has been observed.

Effect of microseparation on contact mechanics in metal-on-metal hip replacements-A finite element analysis. [PDF]

open access: yes, 2014
Some early failures of metal-on-metal (MoM) hip replacements associated with elevated wear have caused concerns for the use of this bearing combination. Simulator studies have shown that microseparation and its associated rim contact and edge loading may

Fully quantitative pixel-wise analysis of cardiovascular magnetic resonance perfusion improves discrimination of dark rim artifact from perfusion defects associated with epicardial coronary stenosis

open access: yesJournal of Cardiovascular Magnetic Resonance, 2018
Background Dark rim artifacts in first-pass cardiovascular magnetic resonance (CMR) perfusion images can mimic perfusion defects and affect diagnostic accuracy for coronary artery disease (CAD).

Error Introduced by a Popular Method of Processing Parallel-Disk Viscometry Data

open access: yesApplied Rheology, 2007
The assumptions implicit in the simplified expressions used to convert the torque-rotational speed data of parallel-disk viscometry into rim shear rate and rim shear stress are identified.

Arthroscopic Fixation of Os Acetabuli Technique: When to Resect and When to Fix

open access: yesArthroscopy Techniques, 2016
Acetabular rim fractures, or os acetabuli, are hypothesized to occur as a result of an unfused ossification center or a stress fracture from repetitive impingement of an abnormally shaped femoral neck against the acetabular rim.

A New CNT-Oriented Shell Theory [PDF]

open access: yes, 2011
A theory of linearly elastic orthotropic shells is presented, with potential application to the continuous modeling of Carbon NanoTubes. Two relevant features are: the selected type of orthotropic response, which should be suitable to capture differences
