Basic Creep-Fatigue Models Considering Cavitation

Abstract Cavitation plays a central role during creep-fatigue. During recent years, fundamental models for initiation and growth of creep cavities that do not involve any adjustable parameters have been developed. These successfully used to predict rupture data austenitic stainless steels again without using parameters. However, it appears basic yet applied creep-fatigue assessments. A summary the cavitation is given. model monotonous deformation transferred cyclic loading. The parameter values are kept except dynamic recovery constant raised due increased interactions between dislocations cycling. This compared with observed LCF TMF hysteresis loops. new cavity plastic presented. formulated in such way condition constrained automatically satisfied. In this way, avoided overestimate rate.
