Prediction of fatigue life of 42CrMo4+QT steel using self-heating effect
Original language description
This study proposes a novel approach that takes advantage of the self-heating effect during cyclic loading, showing promise for the prediction of fatigue life. The self-heating phenomenon offers valuable insight into material behaviour, but the stabilised temperature increase used as the key parameter might be absent in some cases. Introducing a modified version of Fargione’s method, the study addresses such scenarios in the temperature response of specimens from 42CrMo4+QT steel examined here. Experimental investigations on five datasets, each with different machining parameters, analyse how they influence fatigue life and residual stresses. The findings indicate that the proposed approach could also be applied to materials lacking temperature increase. Challenges related to variable-limiting energy are explored, along with proposed solutions for future evaluation. In summary, this study introduces a promising path to assess fatigue life in materials with an unconventional temperature response during cyclic loading.
