Abstract
This paper presents two rather specific applications of holographic interferometry. The first is related to the study of displacements and strains associated with the rapid (200 meter/second) crack propagation in pressurized polymer pipes. Denisyuk type holography using a double pulsed Ruby laser was found to yield practical results; due to the rather explosive nature, experiments were carried out at night, outside of the classical buildings. The other series of tests is concerned with the localization of most stressed zones in prototypes manufactured from steel castings. As the use of brittle lacquers is now prohibited, holographic interferometry was used to find the locations for putting the strain gauges. Relatively large (up to 1 X 1 m) and heavy (about 700 kgs) castings were tested, resting on an unisolated concrete slab, using a semi-professional ESPI system and a small argon laser.
