Dry fault mechanics


Another dry rock friction test.  They should put a hose on it!  Note that when they engage the clutch, there is a big friction jump, but then it settles down to a steady dry friction of 0.5, which is quite high.  Big earthquakes see the friction go down to zero.  That initial spike is probably just a result of the clutch collision.

Adding water should activate proper dynamic friction.  Does the water film actually heat, or does it just interfere with re-adhesion.  Would be interesting....
