| Abstract: | Based on a model considering simultaneously material and uoid type creep damage, a failure probabilistic model for the cree damage is establisheed, After studying the fuzziness of the creep damage for Ni based single crystal superalloys a fuzzy failure probabilistic model is presented. In addition the illustrative catculation shows it is necessary to take the fuzziness of the creep damage in to account when establishing the model. Finally the distributions for random variables in the model are discussed and some result are pointed out. |
