BENCHMARK VALIDATION OF CREEP-FATIGUE ASSESSMENT PREDICTIONS

摘要

Assessment of the performance of high temperature components subject to creep-fatigue loading involves the use of a series of material property model representations. These vary in complexity, depending on the application and the methodology employed. Irrespective of the degree of sophistication of the constitutive equation sets used in analysis, accurate predictions using present day creep-fatigue assessment procedures are dependent on method optimisation to the target material/component class by benchmark testing.
