Summary
Life prediction of C/SiC composites under stress rupture loading conditions was modeled using a Probabilistic Residual Strength (PRS) technique. The model considered the material's initial static strength, time-to-failure, and intermediate residual strength to be random variables. Statistically significant strength and stress-rupture data sets were generated at 1200 °C for this material system as part of an in-house testing program. These data sets were used for the calibration and validation of the PRS model. Predictive features of the model, such as the generation of constant reliability design curves, are presented; and other key benefits of this lifing approach are discussed.
