Correction methods of an apparent negative crack growth phenomenon
Source abstract
Abstract
It often occurs in J−R testing that some initial crack extension (Δa) data points have anomalous negative values. The reason for the apparent negative crack growth is due to the analysis method. The phenomenon as a possible source of error in determining JIC or J−R curve from partial unloading compliance experiments may be eliminated by the compliance correction equation or the offset technique. In this study, new correction methods based on compliance correction and blunting behavior are proposed and verified by the measurement of the actual crack length and JIC analysis.
