초록
SA508 Cl.3 원자로 압력용기강에서 하중변수와 온도가 공기 중에서 피로 균열성장률에 미치는 영향에 대하여 조사하였다. 피로 균열성장률 시험은 12.7mm 두께의 CT(compact tension) 시편을 이용하였으며, 균열길이 추정은 컴플라이언스 방법을 사용하였다. 시험은 0.1, 0.5 하중비와 1, 10Hz의 하중주파수로 상온에서 40
The effect of loading variables and temperature on fatigue crack growth rate in SA508 Cl.3 nuclear pressure vessel steel was investigated in air environment Crack growth rate tests on compact tension specimen of thickness 12mm were conducted by using sinusoidal waveform. The crack length was monitored by compliance method. Test conditions were at 0.1 and 0.5 of load ratio, at 1 and 10 Hz of loading frequency, and at room temperature to 40
