Title: Single particle friction tests with cellulose acetate sphere samples

Abstract

This reporter represents a detailed account of all the experimental work carried out for LLNL using the ''single particle shear cell'' in the department of Chemical Process Engineering of Surrey University, Guildford, United Kingdom. Experimental work with two spheres in contact was performed. Particles were positioned into the specially made sample holders by the micro screws. The contact centres were lined up under the magnifying glass. The behavior of the interparticle contact region between the two spheres was examined by performing the following series of tests: (i) normal force versus normal displacement test, (ii) tangential force limit at gross sliding with increased normal load and decreasing normal load, (iii) tangential force versus micro displacement during initial loading to friction limit and during unloading from friction limit. Work was also performed on single sphere against a flat wall surface. Results are discussed. 34 figs.
