Abstract

Despite the recent rapid growth of numerical techniques and their application in almost every held of engineering experimental techniques have proven an invaluable tool for the investigation of numerous complex problems in academia and industry. Among the various traditional and more recently developed photomechanical technqiues photoelasticity and the method of caustics only will be addressed in this contribution. Problems associated with the interaction of cracks and stress waves, wave focussing, and dynamic contacts will be investigated. Main emphasis will be placed on improved understanding of the underlying physics and therefore, qualitative rather than quantitative results will form the main part of this contribution. However, where necessary, quantitative results will be presented. Applications have been selected in view of showing the wide spectrum of applicability of the optical techniques ranging from micromechanics in electronics to geophysics.
