Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]
, 2013 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
Magazine of Civil Engineering, 2021 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.

Effect of grain size distribution on the shear properties of sand
Frontiers in Materials, 2023 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

Geotechnical Maps for Angle of Internal Friction of An-Najaf Soil-Iraq Using GIS
, 2021 The angle of internal friction value (φ) is used to describe the soil resistance to shear failure. It is estimated experimentally either from Direct Shear Test or Triaxial Stress Tests.

Strength model of a cemented body based on self-compacting characteristics of tailings
Frontiers in Earth Science, 2023 To examine the strength and mechanical characteristics of self-compacting tailings, a direct shear test was conducted under various consolidation states and moisture contents to determine the cohesion and internal friction angle of the tailings.

Comparison of Internal Friction Angles of Soils for Foundation Engineering
IOP Conference Series: Earth and Environmental Science, 2016 The aim of the publication is to evaluate the indicative modules of the deformation of fine-grained, sandy and gravelly soils. Deformation modulus is one of the most important geotechnical properties in terms of geotechnics. The reason is that it is most important from the point of assessing subsidence of buildings and expresses the characteristics ...

Numerical Simulation on Borehole Instability Based on Disturbance State Concept
Energies, 2022 This paper carries out a study on the numerical simulation of borehole instability based on the disturbance state concept. By introducing the disturbance damage factor into the classical Mohr–Coulomb yield criterio, we establish a finite element hydro ...
