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.

Tilt Angle Effect on Friction Stir Welding Conditions

Key Engineering Materials, 2022
In this paper, the effect of tool tilt angle on heat generation and forging force for 1050 aluminum plates, welded by friction stir butt welding, were investigated. Usage of the welding tool with and without pin made it possible to elucidate the particularly reactions of the pin and shoulder on tilt angle variation.

Constant-volume friction angle of granular materials

Canadian Geotechnical Journal, 1988
The postulate that the constant-volume friction angle [Formula: see text] of a granular material is unique and a function of mineral composition is verified experimentally. Granular materials comprised of particles ranging from minerals to metals are tested in a ring shear apparatus.

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.
