Automated Design Of Damage Resistant Structures Volume 1 Theory And Application PDF Download

This report documents an effort to develop an optimality criterion approach to the design of damage tolerant structures subject to stress, deflection, and frequency requirements. Damage conditions are treated in an integral manner in the resizing algorithm. An iterative reanalysis procedure is used to improve the efficiency of the static analyses that are needed as the optimization proceeds. In this volume of the report, the theoretical development is given together with applications to representative structures. Detailed applications include the development of designs for a metal and a composite A7D outer wing panel. Volume II of the report gives user information on the computer program used in these applications.
