Abstract:

By means of an examination of the sensitivity of structural efficiency to mechanical properties of materials, broad evaluations are generated which may serve as structural guidelines for materials development. Results are presented for tension structures under static loading and in fatigue, and for compression structures. Effects of temperature are considered. For evaluation of tension structures, the use of the ductility ratio concept was found to be fruitful. In addition to providing data on structural strength, it also appears to provide an engineering approach to evaluation of material strength under static loading, and to act as a springboard for assessing the sensitivity of materials to fatigue. The sensitivity of compression structures was investigated through the use of results from minimum weight analysis in which weightstrength ratio is expressible in terms of material parameters and the structural design index.
