The report consists of two sections which are closely interrelated in their significance for the stability of rock masses, e.g. rock slides, underground blast caverns, etc. Part 1 deals with stick-slip of selected rocks at different temperatures and under normal stresses up to 20 kgsq cm. Stick-slip was found to dominate the sliding behavior of paired roughly ground surfaces of limestone, basalt, and quartzite. Part 2 of this report presents results from a simple but carefully controlled laboratory experiment to study the relation between dilatancy, sliding friction, and resistance to deformation of densely packed assemblages of steel of Teflon rods.
