Testing of rock climbing anchors in weak sandstone
2014年7月22日 For anchors in weak rock tested in shear, rock crushing was the visible failure mode. Bending of the shaft appears to be the critical property; as the sandstone is weak, bending concentrates load onto the front of the hole and the rock fails, the process repeats itself with greater leverage and less rock till failure occurs.
