The Rock Mechanics Course faces the principle of rock mechanics with particular focus on the physical properties of rock masses and on rock laboratory testing and failure criteria. It will be introduced the concept of rocks stress-strain relationship at depth and showed the procedure to analyze cores to obtained geomechanical indices. Finally, it will be introduced the concept of fracture modelling though stochastic models (Discrete Fracture Network).
Define the characteristics and the mechanical/physical properties (strength and failure criteria) of rock masses and discontinuities; In situ and laboratory testing of rocks and discontinuities; Stress states; Core logging; Introduction to discrete fracture network. Exercises.
