Abstract: A series of experimental results is presented to explore the frictional characteristics of a grease-lubricated journal bearing. Load, grease type, and bushing material are varied to examine their ...

Abstract: A distinctive behavior of an oil-lubricated journal bearing undergoing oscillatory motion is the evolution of friction hysteresis as it traverses from boundary, to mixed, and to hydrodynamic ...

Abstract: A series of experiments was performed to study the behavior of grease-lubricated journal bearings. The results reveal that an oscillatory bearing undergoes a transition from boundary, to mixed, ...

Abstract: Three types of stress-strain relations of high-strength concrete under triaxial compression, axial stress–axial and lateral strain, octahedral normal stress–volume change, and octahedral shear stress-strain curves, are ...

Abstract: The Stribeck curve plays an important role in identifying boundary, mixed, elastohydrodynamic, and hydrodynamic lubrication regimes. Recent advances in elastohydrodynamic lubrication together with ...
