ESDU 72005 provides a method of estimating the stress in thin
flat, or lightly-curved, rectangular stiffened panels under high
intensity acoustic loading. These data are particularly applicable
to aircraft structural panels near, or in the wake of, a jet
engine. A range of sound pressure levels from 100 to 160 dB is
considered and comparisons made with measured data. The method of
analysis assumes individual plates within the stiffened panel
vibrate independently in their fundamental fixed-edge mode. The
r.m.s. stresses given are the nominal rivet line values. A program
implementing the calculation procedure is provided as ESDUpac
A7205.
