Continuum damage mechanics-based creep–fatigue-interacted life prediction of nickel-based superalloy at high temperature
چکیده انگلیسی

This paper presents a creep–fatigue-interacted lifetime prediction methodology based on continuum damage mechanics for the Ni-based superalloy under cyclic loading at high temperature. A unified life estimation model has been developed enabling stress–strain curves and cumulative damage to be predicted. Four types of low cycle fatigue tests were carried out at 650 °C. The effects of the levels of strain range and strain hold time together with frequency characteristics of fatigue behavior on the lifetime were investigated.
