Acoustic fatigue life prediction for nonlinear structures with multiple resonant modes

By: Nasa, National Aeronautics and Space Adm

This report documents an effort to develop practical and accurate methods for estimating the fatigue lives of complex aerospace structures subjected to intense random excitations. The emphasis of the current program is to construct analytical schemes for performing fatigue life estimates for structures that exhibit nonlinear vibration behavior and that have numerous resonant modes contributing to the response.
