MRED 402 ROCK MECHANICS

Stress-strain theory in continuum rock media, constitutive equations, theories of failure, effect of time on strength, excavation and stability of openings, rock classification systems, support of underground works, special issues.

Laboratory exercises: stress-strain calculations, stress invariants, elasticity, plasticity, failure criteria, stress-strain calculations in underground and surface works, wedge and slope stability, sleeve bolts, pole strength, experimental measurements of elasticity, plasticity and strength in uniaxial and triaxial compression, strength in intermediate elongation (Brasil test).
