The Symposium on the Photoelastic Effect and its Applications sponsored by IUTAM with the cooperation of the Permanent Committee for Stress Analy sis and the Society for Experimental Stress Analysis was convened at IBM Ed ucational Center, Ottignies, Belgium, September 9-14, 1973. The subject of the Symposium was the study of the interaction of matter with light in a broad sense. More specifically three main subjects were proposed: (1) Classical and advanced photoelasticity (2) Rheooptics and (3) Theoretical mechanics of a continuum in interaction with the electro-mag netic field. For a better understanding of the problems at hand, three general conferences presented these three subjects and three others treated (4) the available ex perimental methods for measuring the optical properties, (5) streaming dou ble refraction and (6) magneto-and electro-photoelasticity, making a total of six general conferences. The scientific program included also 21 papers. Plen ty of time was provided for discussions after the conferences and after the pa pers. The symposium ended with two concluding conferences followed by a gen eral discussion. In an introductory conference, Professor R. Van Geen (Brussels) has put the study of the Photoelastic Effect in its right place, and given further com ments on the aims of this Syposium.
