Abstract
Crack initiation and propagation were observed on perforated plates at elevated temperature by the CCD video camera. The test specimens are made of SUS304 stainless steel, and temperature is kept to be 550℃, and the geometry of the perforated plate specimens are changed by diameter size of the hole. The photographs of all cycles were recorded to obtain number of cycle of crack initiation(N_c). The results were compared with predictions by the stress redistribution locus (SRL) method and the Neuber's rule's method.
