Abstract
The authors suggest formulating limit state and failure criteria using the known and new stress tensor invariants. The new stress tensor invariants are constructed as average and shear stresses, as well as their ratios in all areas intersected by principal directions of stress tensor. The use of the obtained limit conditions is exemplified in terms of deriving equations of geomedium deformation based on the associated flow law.
