Improved PM gear rolling simulations using advanced material modelling

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
The gear rolling densification of Powder Metal (PM) gears leads to better mechanical properties due to the selectively closed porosity of some hundreds of a micrometer under the surface of the tooth.

Thermodynamics of the densification process for polymer glasses

, 1977
A quantitative description is given for the densification process of glasses resulting from glass formation at elevated pressures . Phenomenological relations are derived, or justified, which allow estimation of the densification rate K' (with respect 10

Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

On the impact of impurities on the densification of polar firn

, 2012
Understanding polar firn densification is crucial for reconstructing the age of greenhouse gas concentrations extracted from ice cores, and for the interpretation of air in ice as a dating tool or as a climate proxy.

Densification model for powder compacts

, 1999
The driving force of densification has traditionally been modeled on the basis of local curvature changes between powder particle pairs. Extension of particle pair analysis to powder compacts involving billions of particles has not been successful ...
