Introduction Rock mechanics...

... Abstract One major objective of rock mechanics testing in a laboratory is to characterize strength and deformational behaviours under in-situ stress state. It is a well-known fact that in-situ rock masses are under a stress state with three principal stresses i.e. triaxial stress state...
