Method and device for predicting fatigue life of hydrogen metal material, medium and product

The invention discloses a method, a device, a medium and a product for predicting the fatigue life of a hydrogen-containing metal material, and relates to the field of fatigue life prediction of hydrogen-containing metal materials. The method comprises the following steps: performing a contrast tensile test and a contrast fatigue test on a sample of a to-be-predicted hydrogen-containing metal material; determining a hydrogen-induced damage sensitivity coefficient-hydrogen fugacity function of the to-be-predicted hydrogen metal material on the basis of a comparison tensile test result; and determining the weekly fatigue damage of the to-be-predicted hydrogen metal material according to the first fatigue test result. According to the hydrogen-induced damage sensitivity coefficient-hydrogen fugacity function, the weekly fatigue damage and the second fatigue test result, weekly hydrogen damage of the to-be-predicted hydrogen metal material is determined; and based on the weekly fatigue damage and the weekly hydro
