The present paper shows the two experimental results for creep-fatigue interaction effects of perforated plate at elevated temperature. (1) The loading history is assumed to be triangle form in fatigue tests, and that in creep-fatigue loading history, the loading rate from compressive strain to tensile strain is assumed to be constant, which vary from fast rate to slow rate in 5 types of strain rate. The slow strain rate loading includes the creep effects to reduce the life span, which is shown to be predicted if the constant loading assumption is assumed. (2) The holding time effect is also investigated. The tensile strain is held to be constant, and holding time is elongated in the present experiments, which is investigated by the fracture analysis.
