Acoustic Fatigue Analysis of Reinforcement Composite Panels

Experience has shown structural components subjected to acoustic excitation can failure due to fatigue.

The estimation of fatigue life for a structure due to acoustic vibrations requires a knowledge of its dynamic response when excited to its natural frequencies by acoustic loadings.

These analysis results will furnish the data for evaluating the magnification factor of the stresses and strains due to vibration against the linear static analysis.

The present paper introduces a dynamic response analysis method for a composite stiffened panel in acoustic fatigue.
