A numerical procedure, as well as the underlying theory and assumptions, is presented for the calculation of the stringer stresses and shear stresses in reinforced panels. The method may be applied to all panel problems in which the loads may be considered acting In the plane of the sheet.nExamples are given to illustrate the use of the method for axially loaded panels with and without rectangular cut-outs and for the covers of box beams with and without rectangular cut-outs.nThe results of this procedure are compared with the experimental data and the approximate engineering methods of analysis of previous NACA papers from which the problems are obtained.
