Summary of results of frictional sliding studies, at confining pressures up to 6.98 kb, in selected rock materials
R. Summers, J. Byerlee
1977, Open-File Report 77-142
This report is a collection of stress-strain charts which were produced by deforming selected simuiated fault gouge materials. Several sets of samples consisted of intact cylinders, 1.000 inch in diameter and 2.500 inches long. The majority of the samples consisted of thin layers of the selected sample material, inserted within...
