The critieal distance theory is suitable for caleulating the creep-fatigue life of complex structures

but the calculation efficiency of this method is very low in engineering. To overcome this shortcoming

Python language was used for the secondary development of Abaqus software. The developed software can calculate the creep-fatigue life of the structure by using the critical distance method. To improve analytical efficiency

various functions were developed in the software

including model information extraction

material parameter import and calculation result output

ete. The applicability of the software was verified by analyzing a high-pressure turbine blade. The results show that the software can efficiently calculate the creep-fatigue life of complex structures by simplifying the steps of the critical distance method

and it has certain engineering value.
