Image correlation is becoming a popular full field optical experimental technique in wide range of applications because it is cheap, fast and easy. It performs equally well at the micro and the macro scales and requires minimal surface preparation. In this work the 2D image correlation technique was used to measure the in-plane displacement fields near the crack tip. Commercial image correlation software DaVis 6.0 by LaVision was employed.
