Therefore, the displacement transducers must be in locations where the risk is that additional displacements originating from deficiencies in the test system will be measured causing too low normal loads to be applied. Herein, this issue is investigated in a new 5 MN direct shear test setup. The system...

.... Introduction Rocks subjected to constant load, or constant displacement boundary conditions can be observed to deform slowly and eventually fail at stress levels less than otherwise expected from short-term strength tests (Amitrano and Helmstetter, 2006). Similarly, rock mass failures commonly don’t occur...
