Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]
The cylinder bore surface texture, widely produced by the honing technique, is an essential factor for a good engine performance (friction, oil consumption, running-in, wear etc.).

Failure Mechanism and Slope Factors for a Footing Resting on Slopes
The behaviour of a footing affected significantly with the presence of the slope. The effect of slope on the bearing capacity, slope factor, and failure mechanism has been explored using limit analysis.

Effects of a straight oil on friction at the tool-workmaterial interface in machining [PDF]
Authors would like to express their gratitude to the TOTAL Company for the furniture of the lubricant.The quantification of friction coefficient along the tool-workmaterial interface in machining remains an issue in tribology. This paper aims identifying

Effect of grain size distribution on the shear properties of sand
In this study, we investigated the effect of particle size distribution on the shear properties of sand. Direct shear tests were conducted using four types of sand samples with different particle size distributions obtained from standard sand produced by

Internal friction investigation of phase transformation in nearly stoichiometric LaMnO3+δ [PDF]
Rhombohedral LaMnO3+δ powders, prepared by two different soft chemistry routes (co-precipitation and hydrothermal synthesis), are sintered at 1400 °C for 2 h in air. Measurements of internal friction Q−1(T) and shear modulus G(T), at low frequencies from
