ABSTRACT:
A system for applying a controlled stress on a joint in a structure includes means for applying a plurality of thermal bursts in a designated timing sequence and trajectory pattern to produce a combined shock wavefront directed toward the joint. This system can provide increased accuracy in measuring the strength and quality of composite bonds and laminations.
