摘要：
The analysis of the methods used for the evaluation of forces required for the opening of the tip of a fatigue crack enables us to choose and substantiate the approach to the evaluation of current values of the crack-tip opening displacement. On the basis of this approach, we propose an original procedure for measuring current values of the crack-tip opening displacement for a propagating fatigue crack at a constant distance behind its tip. © 2002 Plenum Publishing Corporation.
