Abstract:
Based on Haddad's small crack theory, a new comprehensive fatigue life model of the TC4 titanium alloy is proposed through combining the modified Chaboche model and the crack propagation formula considering the crack closure effect. The results of model validation and comparisons show that the crack initiation life and crack propagation life predicted by the model are consistent with the test data under cyclic loading of the alloy.
Keywords:
TC4 titanium alloy, crack closure, crack initiation, crack growth, life prediction.
