Stresses in reinforcing rings due to axial forces in cylindrical and conical stressed skins

Stresses in reinforcing rings due to axial forces in cylindrical and conical stressed skins

Date: January 1, 1938
Creator: Drescher, K & Gropler, H
Description: At the ends of a monocoque fuselage concentrated axial forces in the skin must generally be taken up. Such axial forces must also be taken up in the case of other members where axial forces from the neighboring stressed skin construction must be considered. In order to take up these axial forces two bulkheads or reinforcing frames may be arranged at the positions where the forces are applied. If these bulkheads are in the form of rings, bending moments are set up in them. In the present paper computations are performed for obtaining the value of these bending moments.

Stresses in single-spar wing constructions with incompletely built-up ribs

Stresses in single-spar wing constructions with incompletely built-up ribs

Date: January 30, 1940
Creator: Reinitzhuber, F
Description: It is shown that the force distribution resulting from incomplete ribs in single spar wing structures may be determined with the aid of the shear field method by a statistically indeterminate computation. A numerical computation is given of the force distribution of a wing structure whose two neighboring incomplete ribs with web missing in half the section are torsionally loaded.

The stresses in stiffener openings

The stresses in stiffener openings

Date: February 1, 1942
Creator: Marguerre, K
Description: The present study treats as a typical example a ring the center line of which is produced by the intersection of two circular cylinders of different diameter. Three load cases are analyzed: (1) Axial and circumferential stresses in both cylinders, the cylinder stresses themselves to be in the ratio conformal to the cylinders loaded under internal pressure. (2) Pure longitudinal tension in the large cylinder. (3) Pure shear (torsion) in the large cylinder. To simplify the calculation, it is assumed that the ring, compared to the shell, is very strong, so that its deformations have no perceptible effect on the stress condition in the shell. This provides an upper limit for the ring stresses actually produced in a shell design, for, according to the theory of stressed skin statics the shells, by elastic flexibility of the ring, regroup the forces deposited on it in such a manner that the ring is relieved.

Stresses Produced in Airplane Wings by Gusts

Stresses Produced in Airplane Wings by Gusts

Date: January 1, 1932
Creator: Kussner, Hans Georg
Description: Accurate prediction of gust stress being out of the question because of the multiplicity of the free air movements, the exploration of gust stress is restricted to static method which must be based upon: 1) stress measurements in free flight; 2) check of design specifications of approved type airplanes. With these empirical data the stress must be compared which can be computed for a gust of known intensity and structure. This "maximum gust" then must be so defined as to cover the whole ambit of empiricism and thus serve as prediction for new airplane designs.

Stresses produced on an airship flying through gusty air

Stresses produced on an airship flying through gusty air

Date: September 1, 1922
Creator: Munk, Max M
Description: The stresses produced by gusts are proportional to the speed of the airship. At highest speed they are of the same range of magnitude as the stresses during the creation of a large dynamic lift.
