... ABAQUS’ UMAT subroutine. The result agrees well with the analytic solution. The new damage model for rock matches the theoretical expectations, and shows that the proposed model can predict anisotropic damage. reservoir geomechanics Simulation damage criterion hydraulic fracturing Brazilian...

... salt demonstrate that damage can be modeled in terms of stress invariants. In this paper the DRZ extent is calculated based on a dilatant damage criterion. The calibrated damage factor C in the damage criterion is determined by comparing ultrasonic wave velocity field measurements obtained in the S-90...
