One major source of error commonly encountered in determining the fatigue life of a given element arises from the loads involved, which are usually of random nature. As a rule, resistance analyses, carried out by simulation or tests, are done by using a loading history accounting for the real loads
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
