Abstract : The year 1 effort was split between laboratory development and research. A smart materials laboratory was developed for research on the mechanics of electro-mechanical coupled materials. The laboratory includes sample preparation, test facilities, and failure analysis tools as described below. There are presently four graduate students working on this research, one at the masters level and three at the Ph.D. level. There have been two conference proceedings articles and one journal article submitted. This will substantially increase in the coming year. The PI has made four presentations of research results and will make an invited presentation in July, 1997. The PI is presently working on several related programs described below. Departmental support from Georgia Tech is being used to perform work in excess of the original scope of this project.
