Abstract

The present paper reports a new discrete complex compliance spectra method in which each frequency component is a direct function of stress and relative density. Comparisons between model calculations and experimental measurements show that the model exhibits excellent quantitative agreement at all experimental stress-relative density states and significantly smoothes the experimental input data. It is anticipated that design engineers will use the present method to accurately predict the creep strain histories resulting from a broad range of specific stress-relative density combinations.
