The inward bulge type buckling of monocoque cylinders 1: calculation of the effect upon the buckling stress of a compressive force, a nonlinear direct stress distribution, and a shear force
"In the present part I of a series of reports on the inward bulge type buckling of monocoque cylinders the buckling load in combined bending and compression is first derived. Next the reduction in the buckling load because of a nonlinear direct stress distribution is determined. In experiments nonlinearity may result from an inadequate stiffness of the end attachments in actual airplanes from the existence of concentrated loads or cut-outs" (p. 1).

The Inward Bulge Type Buckling of Monocoque Cylinders 2: Experimental Investigation of the Buckling in Combined Bending and Compression
This paper is the second part of a series of reports on the inward bulge type buckling of monocoque cylinders. It presents the results of an experimental investigation of buckling in combined bending and compression. In the investigation it was found that the theory developed in part I of the present series predicts the buckling load in combined bending and compression with the same degree of accuracy as the older theory does in pure bending.

Simply Supported Long Rectangular Plate Under Combined Axial Load and Normal Pressure
Note presenting a solution for the load-strain curve of a simply supported rectangular plate with a width-length ratio of 1:4 under combined normal pressure and axial load. The results indicate it to be conservative design in the elastic range to neglect the effect of lateral pressure on the sheet buckling load and on the load carried by the sheet after buckling.

Torsion Test to Failure of a Monocoque Box
Note presenting a torsion test to failure for a monocoque box of 24S-T aluminum alloy. The box had a rectangular section and was reinforced by Z-stringers, antirolls, bulkheads, and corner posts.
