“…Materials/structures are usually bearing complex loading during service process. 1 Generally, materials/ structures, such as turbine blades, undergo from low cycle fatigue (LCF) loading created through start-up and stop and high cycle fatigue (HCF) loading caused by high frequency vibration. 2 It should be noted that the damage type of some materials/structures is the coupling damage of low cycle fatigue and high cycle fatigue, rather than pure LCF or pure HCF damage.…”

It is very important to establish a life prediction model that evaluates the combined high and low cycle fatigue (CCF) damage of materials. Based on the toughness exhaustion, this paper develops a CCF life prediction model considering loading interaction effect. The loading interaction factor is proposed to reflect the interaction effect between high cycle fatigue and low cycle fatigue. The proposed model does not require any additional material parameters and is convenient for application. The experimental data of four materials including GH4033 Ni-basis alloy, TC11 titanium alloy, LY12-CZ aluminum alloy, and 45 steel are applied to verify the proposed model. Comparing the prediction results of the proposed model with the Miner’s rule and the T-K model, the results show that the predicted results of the proposed model are more satisfactory.
