In this paper, on the basis of Ref. [1], stresses, deformations, stability and natural frequencies are calculated and analysed for orthotropic laminated, sandwiched and stiffened rectangular shallow shells. The following formulas are obtained in which generalized displacements u0, v0, rx, ry and w are used: (1) formulas for calculating critical loads under the action of membrane forces Nx, Ny and Nxy, (2) formulas for calculating stresses and deformations under the action of external loads mx, my, qx, qy and...

In this paper, on the basis of Ref. [1], stresses, deformations, stability and natural frequencies are calculated and analysed for orthotropic laminated, sandwiched and stiffened rectangular shallow shells. The following formulas are obtained in which generalized displacements u0, v0, rx, ry and w are used: (1) formulas for calculating critical loads under the action of membrane forces Nx, Ny and Nxy, (2) formulas for calculating stresses and deformations under the action of external loads mx, my, qx, qy and qz, (3) formulas for calculating natural frequencies under the influence of initial membrane forces and inertias p, Q and I. These formulas involve only algebraic operations and can be readily evaluated by means of electronic computers and it is also possible to obtain optimum design by changing the parameters. Finally, it should be pointed out that the formulas are valid both for large or small shear rigidities.

The k- ε two- equations turbulence model is used to close the time-averaged governing equations for the flow field. The finite difference equations in th& calculated region have been derived with the volume control method. A new approximation of the sub-laminar layer is adopted for the wall boundaries to give a higher calculating accuracy and a simplified programme. A programme using Gauss-Seidel iteration has been developed to be run on a PDP-11/70 computer and it is shown that it is convergent. An experiment has been performed in a test wind tunnel to check whether the prediction is correct. The velocity field is measured with a hot-wiremeter, but in the recirculating region of the flow field it is measured with a pitometer with a probe of flow direction. The temperature distribution is measured with fine copper-constantan thermo-couples. The experimental results agree fairly well with those by the numerical prediction.
