Abstract
High sensitivity Moire´ interferometry has been applied to the study of dovetail joints as found in turbomachinery. Without physical measurements, the true contact conditions cannot be known. The benefits to be gained when coupled with a finite element stress analysis are discussed. It is concluded that Moire´ interferometry is of great potential in the study of fixed mechanical joints.
