Abstract
A procedure for characterising the stress strain rate field for fractu re of creeping materials using Norton's law by finite element method h as been developed. C has been found to be the characterising paramete r. Time to crack initiation, t(c), has been calculated with critical C TOD as the criterion for crack initiation. The stress and the strain-t ime relations and the equivalent stress and equivalent strain contours have been drawn. Biaxial load effects are studied in detail.
