    Abstract:
    A generalization of the Ramberg-Osgood model for three dimensional cyclic loading was formulated for rocks in the previous paper using discretized kinematic hardening concepts. Here, material functions are interpreted and calibrated. Perfect hysteresis, cyclic strain accumulation and fatigue are analyzed for typical loading histories.
