Abstract: Two stress relaxation constitutive models have been developed to predict the stress relaxation behavior for hightemperature bolting according to continuum damage mechanics, Kachanov–Robatnov (K–R), and Othman–Hayhurst ...

Abstract: With the development of ultrasupercritical power generation technology, creep strength of hightemperature materials should be considered for safety evaluation and engineering design. However, longtime creep testing should ...
