Abstract
Numerical contour integrations of the creep crack C∗ integral were carried out for two types of specimen. The results agree reasonably well with C∗ evaluations using limit analysis methods; path-independence of C∗ is shown. A realistic definition of the creep pseudo-stationary state is proposed and various forms of creep data input are discussed.Keywords
