The paper shows the derivation of integral fracture concept from conservation laws of general continuum mechanics. Its applicability to cracks under steady- state creep conditions is demonstrated experimentally. The numerical procedure necessary for a reliable evaluation of the crack driving parameter from experimental data is discussed.
