Available in PDF, EPUB and Kindle. Book excerpt: Results are presented of an experimental investigation of the general instability of reinforced thin-walled metal cylinders subjected to pure bending and pure torsion over a range of geometrical quantities and structural sectional characteristics. Based on the experimental results and an existing theory of unstiffened metal cylinders, parameters were evolved which make possible an estimate of the stress at which general instability will occur for any given stiffened metal structure of circular cross section.

Available in PDF, EPUB and Kindle. Book excerpt: As part of a general program to determine the applicability of linear orthotropic theory to the design of cylindrical shells under various loading conditions, a theoretical and experimental investigation was performed on the general instability of orthotropic cylinders under bending and combined axial compression and bending loading. Based on a simple approximation for the asymmetric buckling pattern, theoretical results suitable for design use were obtained for the buckling of orthotropic cylinders for both bending and combined loading conditions. It was shown that the buckling stress for orthotropic cylinders under bending or axial compression loading are equal which agrees with previous results for isotropic cylinders. Theoretical results were evaluated by means of a series of careful experiments performed on orthotropically stiffened cylinders designed to fail in the elastic general instability mode. For both bending loading and the combined axial and bending loading condition, experimental results were in good agreement with the theory.

This book was released on 1966 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented to determine the general instability load of a ring-stiffened corrugated cylinder under axial compression. This method is developed using linear small deflection theory. The stiffness properties of the rings are uniformly distributed along the cylinder and the eccentricity of the rings with respect to the corrugation centerline is taken into account. Analytical and experimental results are compared. In this comparison good agreement is obtained for cylinders loaded in pure compression. For the cylinders subjected to bending or a combination of bending and compression the analytical calculations are conservative. A computer program for the application of this method has been developed. The program and an explanation of its notation are included in this report.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical buckling stresses are determined in explicit form for circular cylinders with circumferential and axial stiffening. The loadings are axial compression, radial pressure, hydrostatic pressure, and torsion. Analyses were confined to moderate-length and long cylinders. The investigation was based upon the use of a form of Donnell's equation derived by Taylor which is applicable to orthotropic cylinders. The derivation of this equation is presented in this report.

This book was released on 1962 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of curves for use in determining the elastic general-instability pressure of ring-stiffened cylindrical shells based on the equations of Kendrick and Bryant is presented. Also, several convenient formulas developed by other investigators are discussed. Numerical results obtained from these methods of solution are presented in tabular form for comparison. The pressures determined from the graphical solution of the Kendrick Part III analysis agree more closely with pressures predicted by Kendrick's equations than by other methods presented and are more easily obtained.

Available in PDF, EPUB and Kindle. Book excerpt: The general applicability of orthotropic stability theory to aerospace shell structures was examined experimentally. For this purpose a series of careful experiments were performed on orthotropically stiffened cylinders designed to fail in the elastic general instability mode under three separate loading conditions: axial compression, torsion and hydrostatic pressure. Experimental results obtained during the program verified that for all loading conditions considered linear orthotropic theory results in accurate predictions of cylinder strength. As a result of observed discrepancies between experiment and previously existing theory for longitudinally stiffened cylinders under axial compression, theoretical studies were initiated which resulted in the discovery of a new asymmetric failure mode for this cylinder configuration. Based on this new failure mode, good correlation between experiment and theory was obtained except when the longitudinal stiffened cylinder configurations approached that corresponding to an isotropic cylinder. Other theoretical investigations performed during the program established that cylinder boundary conditions have a pronounced effect on the buckling strength of orthotropic cylinders under hydrostatic pressure loading.
