The paper deals with strong geomaterial samples weakened by a family of randomly distributed fissures (or cracks). Fissures are filled up with a weak Tresca-type material. The effect of strength reduction is analyzed employing a probabilistic modelling. Complete closed-form solutions are derived for both randomly isotropic and randomly anisotropic samples. The role of the number of fissures and their orientation (localisation) is discussed in numerical examples.
