One possibility to intervene in falls due to slipping is to use shoes with soles that can resist possible slips. The objective of this research is to evaluate the friction coefficient of the female footwear for the elderly ...

The experimental flow stress curves of structural steels obtained from axisymmetric compression tests conducted under hot-working conditions very often include the frictional effects present at the tool/specimen interface. ...

The purpose of this work is to study the influence of abrasive wear modes on the coefficient of friction (μ) of thin films. Initially, free rotative-ball micro-abrasive wear testing equipment was designed and constructed ...

Eight different models to represent the effect of friction in control valves are presented: four models based on physical principles and four empirical ones. The physical models, both static and dynamic, have the same ...

Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous suspensions of sucrose and bentonite. The rheological properties of these suspensions were ...

The micro-scale abrasive wear test by rotative ball has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Two wear modes are usually observed in ...

Recently, it has been shown theoretically how the lithospheric stress changes could be linked with magnetic anomalies, frequencies, spatial distribution and the magneticmoment magnitude relation using the electrification ...
