Interface of materials and structures on airframes Part I. basic design considerations

The interface of materials and structures is of particular importance during the early design phases of an aircraft when decisions regarding the choice of material and corresponding structural configuration have to be made. This part of the design process is considered from the viewpoints of materials, structures, and design engineers. While welldefined problems in each of these fields are in the hands of competent specialists, it is shown that major problems also exist in the ill-defined regions between these specialties and have beckoned vainly for any systematic approach toward their solution. These problems are identified and steps toward their solution are recommended in some detail. The present report covers the first phase of a project under the title Interface of Materials and Structures on Airframes. This project is supported by: Naval Air Systems Command Work Request No. WR-9-7060 dated 26 June 1968
