National Advisory Committee for Aeronautics, Technical Notes - Critical Stress for an Infinitely Long Flat Plate with Elastically Restrained Edges Under Combined Shear and Direct Stress
A simple interaction curve is presented for evaluat-
ing the conditions of combined shear and direct stress
under Which an infinitely longI flat plate with equal
elastic restraints against rotation along the edges will
become unstable. The theoretical work that led to the
interaction curve is presented in the form of appendixes.
In the design of stressed-skin structures, considera-
tion must sometimes be given to.ths critical stresses for
a sheet under a combination of shear and direct stress.
The upper surface of a wing in flighti.for example. may
be subjected to combined shear and compressive stress and
the lower surface to combined shear and tensile stress
simultaneously. Under this condition the upper surface
may'buckle at a lower compressive stress than if the shear
were-not present and the critical shear stress for the
lower surface will be increased by the presence of the
tensile stress. The purpose of the present report is to
specify the combination of shear and direct stress under
which such.surfaces may be expected to buckle.
