Prediction of tensile curves, at 673 K, of cold-worked and stress-relieved Zircaloy-4 from creep data

A constitutive creep equation, based on jog-drag and cell-formation, is used to predict tensile curves from creep data obtained in the same material. The predicted tensile curves are compared with actual stress versus plastic strain data, obtained both in cold-worked and stress-relieved specimens. F...
