Zusammenfassung: | The invention belongs to the technical field of safety evaluation, and discloses a stress corrosion prediction method and device, equipment and a storage medium. According to the method, transient analysis is carried out by obtaining the surface defects of the thin-walled tube, the residual stress and the equivalent plastic strain value of the surface defects of the thin-walled tube are determined, finite element simulation is carried out on the residual stress and the equivalent plastic strain value to obtain test data, training optimization is carried out on a prediction model according to the test data, and the prediction accuracy of the thin-walled tube is improved. Compared with the prior art, the method has the advantages that under the experimental condition of accurately controlling other parameters, the simulation test samples with the surface circumferential dents with different depths and different morphologies can be quantitatively prepared; key test data are obtained, and then a stress corrosion |
