Some Remarks on Improved Analysis for Flexural Creep with Application to Sialon Ceramics



Tze J. Chuang


An earlier paper co-authored by the present author contains a major assumption in the analytical method that not be valid in a general class of structural ceramics. A more-rigorous mathematical analysis without this assumption has been performed, and the closed-form solutions of the description of the asymmetric power-law creep behavior are presented. The results presented here should be regarded as further improvements to the original paper, as they are applicable to a more general case without such an assumption. Using the two loading cases as a numerical example, the present solutions indicate that, in the case of sialon ceramics, the original predictions on the stress exponents are still valid. However, the predictions on the pre-exponent constants differ from one to three orders of magnitude, because of error propagation.
