STIA

A low cost, rapid replica method has been developed to monitor the whole strain field near for example, welds, cracks and other sharp stress raisers. The technique uses transparent replicas that can be combined in several different ways to produce optical interference patterns representing the strain information. Several examples of the use of the technique are described.
