Damping, cyclic strain buildup and fatigue of rocks a generalized Ramberg-Osgood approach

A generalization of the Ramberg-Osgood model three dimensional cyclic loading was formulated for rocks in the previous paper [1] 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. © 1992.
