The present study presents a theoretical, analytical and experimental study of the engineering prediction of shearography fringe pattern. A methodology was developed and implemented as an easy to run simulation that can evaluate LST fringe pattern in advance. It focuses on a circular delamination flaw stimulated by vacuum excitation. It shows a good agreement with the performed experimental results.
