Crack length an d plastic zone size measurements were made on a limited number of mild steel tensile specimens of ASTMGS No.3.5 and No. 7.0 grain size for various stress amplitudes and various mean stresses. The data are in agreement with the predictions of Silby, Cottrell and Swinden concerning the

The creep zone boundary has been somewhat arbitrarily defined by Riedel [1,2] as, by equating the equivalent creep strain to the equivalent elastic strain, c"=e o~ ! So the creep zone boundary r (0, t) can be approximated by using the HRR-creep strain field. This leads to
