Low-cycle fatigue crack propagation has been modeled successfully by an equation employing the cyclic J-integral, A/. The use of this equation in practice is hindered by the difficulty of calculating AJ. A load-deflection hysteresis diagram must be obtained to estimate its value for several points o
A new model of fatigue crack propagation is proposed which takes the effect of cyclic stress ratio into account. In the model it is assumed tbat the fatigue cmck propagation rate is proportional to the absorbed hysterisis energy per stress cyck at the tip of a crsck. The energy is calctdated from st
