heal.abstract	On the basis of an extensive experimental program of axisymmetric triaxial compression and extension tests, the mechanical behaviour of a weak sandstone (Red Wildmoor sandstone) is analysed and modelled within the frame of the theory of elastoplasticity. Stress-dependent elasticity and damage are incorporated into the model. Pressure sensitivity of the plastic behaviour is described through a non-linear Mohr-Coulomb model with friction hardening and cohesion softening. Emphasis is given on the calibration procedure. Validation of the model is done through back analysis of the experimental tests. Shear-band analysis is performed on the basis of the extension of the constitutive model to non-coaxial plasticity.
