Description
Based on Schlottner-Seele average creep rupture rate theory and relaxation function, this paper constructs a relaxation damage model, with which to predict the relaxation damage life of high temperature bolting material 1Cr10NiMoW2VNbN. Validation results of relaxation tests indicate that the developed model has led to better consistent results with the experimental data. (authors)
