A series of interdisciplinary design courses being offered to senior and graduate engineering students at the University of Washington is described. Attention is given to the concepts and some of the details on group design projects that have been undertaken during the past two years. It is noted that ceramic materials normally demonstrate a large scatter in strength properties. As a consequence, when designing with these materials, the conventional 'mil standards' design stresses with acceptable margins of safety cannot by employed and the designer is forced to accept a probable number of failures in structures of a given brittle material. It is this prediction of the probability of failure for structures of given, well-characterized materials that forms the basis for this series of courses.
Problems faced by the universities due to the drop in enrollment of aeronautics and astronautics undergraduate students are examined. Efforts made by the universities to overcome some of these problems are discussed. The author presents ten specific recommendations involving government and industry support to overcome the apparent lack of interest in engineering disciplines.
