Abstract
The paper presents results of numerical modeling by application of plastic constitutive models with various failure criteria. The Balmer’s and Balandin’s failure criteria have been elaborated in FISH language and they have been applied to simulate two basic problems which are: compression of rock sample and construction of excavation in rock mass.
