Research Summary for the Period 1 October 1970 to 30 September 1975.
Abstract
Designers of high-performance aircraft and space vehicles are constantly confronted with the problems of optimal use of structures and their elements. They face severe constraints with respect to weight and safety, and these, in turn result in major problems of accurate prediction of stresses, deformation, and natural frequencies. Many simplified (approximate) theories have emerged which make it possible to construct mathematical models that are more or less amenable to analysis. These models are usually restricted to certain limited geometric shapes (rods, beams, plates, shells, etc.) and the extent of their accuracy is not fully understood. This problem has been approached in a different manner with the help of the present AFOSR grant. The primary purpose of the research was the study of forced motion and stress waves in plates, shells, and rods. C comparative study between mathematical models of varying sophistication was conducted.
