Abstract:

Analytical results for estimating natural frequencies and stress response for conventional stiffened flat panels, two-sided box structure, wedge structure, and unstiffened cylindrical panels are presented. Acoustic fatigue tests of twelve stiffened flat panel and six box structure designs, two specimens for each design, were used to develop design equations for estimating acoustic fatigue resistance of skin, stringer, and rib structure. Computer programs are presented for estimating frequencies of stiffened flat panels, box structure, and wedge structure. Nomographs are presented for skin design and curved panel stress response.
