FABRICATION OF STRUCTURAL SPECIMENS FOR THE INVESTIGATION OF PEAK PRESSURE AND MULTI-MODE EFFECTS OF SONIC FATIGUE

Abstract

The report describes the analysis, design and fabrication of structural specimens to be used in an investigation of peak pressure and multi- mode effects of sonic fatigue. These specimens are to be fatigue tested to failure. Details of the analysis and design are presented for three-bay panels and frame stringer panels. The three-bay panels were designed to fatigue in 100,000 cycles when exposed to an SPL of 162 db. A linear structural response approach is used, and the possibility of nonlinearities is examined. The frame stringer panels were designed to withstand various combinations of internal bursting pressures and external aerodynamic loads. Procedures used in fabricating the above specimens, and specimens designed by R and D personnel are also described.
