Measurements of the angle of interparticle friction

Géotechnique, 1974
The coefficient of interparticle friction φμ is defined, and its theoretical basis and conventional methods of measurement are briefly introduced. A new apparatus, designed to measure the value of φμ obtaining at a single particle–particle contact, is described with emphasis upon the materials examined, their preparation and data analysis.

A note on the choice of interfacial friction angle

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1996
Estimates of interfacial friction angle (delta) are necessary for the design of retaining structures and deep foundations, Recommendations in the literature regarding delta values are often contradictory and are therefore not easy to apply in geotechnical design, A critical examination of past studies in terms of data generation techniques used and ...

Angle of Internal Friction for Pond Ashes

Journal of Testing and Evaluation, 2000
Abstract Thermal power stations use pulverized coal as fuel, producing enormous quantities of ash as a waste product of combustion. Nearly 800 million metric tons of ash is produced each year all over the world. In India, presently 97 million metric tons of ash is produced annually by power stations.

Hypoplasticity for soils with low friction angles

Computers and Geotechnics, 2004
Abstract Hypoplasticity has been proven to be successful in reproducing the mechanical behaviour of sands. However, in case of clays the incremental stiffness in shear is predicted too low. An investigation of the hypoplastic equation based on the analysis of response envelopes reveals the reason of this deficiency.

Critical state friction angle of sands

Géotechnique, 2011
The friction angle is the most important parameter used for analysing the response of sands to loading. However, its variation with stress level, fabric and particle damage has been debated. This study examines the yield and critical state friction angles of three sands using triaxial compression and ring shear tests.

Angle of repose and internal friction

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1966
Abstract The relation between angle of repose and angle of internal friction in a fragmented mass is discussed, and experiments with crushed rocks are reported. It is concluded that the angle of repose is not generally the angle of internal friction of the material in the pile, but of the same material in a more closely packed condition.

Force distribution by optimizing friction angles for multifinger system

[1993] Proceedings IEEE International Conference on Robotics and Automation, 2002
An efficient way of finding the force distribution by optimizing the contact friction angles, which are the angles between the contact forces and contact normals, for multifinger grasping systems is developed. Three steps (projection, residual wrench equilibrium, and optimization) are proposed to solve the force distribution problem.
