A strain energy theory is developed for the calculation of the critical load for the inward bulge type of general instability of reinforced monocoque cylinders subjected to pure bending. The deflected shape at buckling is assumed to be represented by an expression containing eight free parameters in addition to the two characterizing the wave lengths of the circumferential and axial directions. The theory is applied to two representative cylinders of the GALCIT test series and to two of the PIBAL series. The critical stresses calculated are 8.3 to 22.9 percent higher than the experimental values.

The experiments conducted with boron carbide and each of four metals showed that nickel, cobalt, and iron formed a bonding zone between the metal and the ceramic and that chromium showed satisfactory physical wetting characteristics on the ceramic.

As a first step toward the computation of the velocity distribution along a wing profile of arbitrary shape in a compressible fluid, the circulation-free flow around a symmetrical profile is treated under the assumption of the simplified density-speed relation due to Tchaplygin, Karman, and Tsien. The velocity distribution problem is reduced to a nonlinear integral equation which is solved by a fairly rapidly convergent iteration method. Numerical examples are given.

A systematic account is given in Part 1 of the use of dimensional analysis in constructing similarity conditions for models and structures. The analysis covers large deflections, buckling, plastic behavior, and materials and nonlinear stress-strain characteristics, as well as the simpler structural problems. Part 2 deals with the testing of square plaes in shear, with and without holes.
