... to be higher than the values found from conventional low confinement compression tests. This is to be expected, since the punch test predetermines the location of the failure plane whereas the failure plane in a triaxial compression test will occur at the dominant plane of weakness.

... an essential and necessary part of the stick-slip process. The amount of premonitory slip before an event increases with increasing confining pressure, decreasing displacement rate, increasing total shear displacement along the sliding surface, and when the precut is water saturated. In all of these cases...
