“…This prediction is in reasonable agreement with the range obtained from the experiments (60-85 MPa), reaffirming the poor notch sensitivity associated with LCF fracture at the test temperature. Furthermore, the extreme sensitivity of the fracture time to the presence of matrix cracks is consistent with the oxidation embrittlement characteristics of other SiC-based CFCCs at intermediate temperatures [12,15,17,22,23,27,38].…”
