The methodology of the complex analysis of strains and stresses for finite-element modelling of thrusting

The technique of the complex analysis of results of the finite-element 2D-modelling of thrusting is proposed. It includes visualization of elastic and plastic strains or stress tensor components and its invariants also: hydrostatic pressure, maximal tangential stress and stress ratio. The trajectories of principle stresses and lines of sliding are constructed for mapping of the compound stress state structure. We use Byerlee’s criterion for determination of the possible fracturing zones.
