ESDU 73014 gives a method of estimating the r.m.s. stress at
three points in the skin of a rectangular plate between flexible
stringers (that may be of a different material) in a flat
skin-stringer panel. The points are at the plate centre and in the
middle of both the short and long sides. The method also gives the
stress in the stringer. To ease the use of the method, graphs are
given of two parameters required in a simple estimation equation.
Predictions are compared with results of tests from a number of
sources for both built-up and integrally-machined panels. A program
that estimates the fundamental natural frequency of the panels and
the r.m.s. stresses is also provided as ESDUpac A7314.
