Here is a paper showing how fatigue damage can be calculated from a stress response PSD for a plate excited by an acoustic pressure field: acoustic_fatigue_plate.pdf
The calculation method is given at:
Fatigue Damage for a Stress Response PSD

The Matlab scripts for calculating the plate responses are included in the vibroacoustics section of the Vibrationdata GUI package, available at: Vibrationdata Signal Analysis Package
