Abstract	This study investigates the effects of creep behavior on fatigue strength of the perforated plate at elevated temperature, when Stress Redistribution Locus (abbreviated as SRL) method is applied for the perforated plate. The creep-fatigue test is carried out by using the specimens made of SUS304 stainless steel at the temperature of 550°C. The trapezoidal wave having tensile hold time at peak strain is assumed. The geometry of the perforated plate specimens are changed in the same manner as the fatigue test by varying number or diameter-size of through holes. The linear damage rule for fatigue and creep is assumed, and the comparison between the experimental results, namely the SRL method evaluation at the Campbell’s diagram will be made. Both of the load and displacement are measured in all the cyclic history of the loadings to clarify the relation between crack initiation or propagation and the load decrease from the viewpoint of direct observation of crack at the holes side.
