A CDM-BASED STUDY OF FATIGUE-CREEP INTERACTION BEHAVIOR

摘要：

Based on the ductility dissipation theory and effective stress concept of continuum damage mechanism, a new fatigue-creep damage model is developed. As to 1.25Cr0.5Mo steel, series of high temperature stress-controlled fatigue-creep interaction experiments were carried out, and the damage evolution laws under various conditions are derived. Results indicate that the damage model presented in this paper are applicable to describe the damage evolution of fatigue-creep interaction under stress-controlled mode.
