Stresses around rectangular cut-outs in skin-stringer panels under axial loads - 2 by Paul Kuhn( )

4 editions published in 1943 in English and held by 128 WorldCat member libraries worldwide

Cut-outs in wings or fuselages produce stress concentrations that present a serious problem to the stress analyst. As a partial solution of the general problem, this paper presents formulas for calculating the stress distribution around rectangular cut-outs in axially loaded panels. The formulas are derived by means of the substitute-stringer method of shear-lag analysis
Critical combinations of longitudinal and transverse direct stress for an infinitely long flat plate with edges elastically restrained against rotation by S. B Batdorf( )

4 editions published in 1946 in English and held by 127 WorldCat member libraries worldwide

A theoretical Investigation was made of the buckling of an infinitely long flat plate with edges elastically restrained against rotation under combinations of longitudinal are presented that give the critical combinations of stress for several different degrees of elastic edge restraints Including simple support and complete fixity. It was found that an appreciable fraction of the critical longitudinal stress may be applied to the plate without any reduction in the transverse compressive stress required for buckling
Description of stress-strain curves by three parameters by Walter Ramberg( )

3 editions published between 1943 and 1947 in English and held by 121 WorldCat member libraries worldwide

A simple formula is suggested for describing the stress-strain curve in terms of three parameters: namely, Young's modulus and two secant yield strengths. Dimensionless charts are derived from this formula for determining the stress-strain curve, the tangent modulus, and the reduced modulus of a material for which these three parameters are given. Comparison with the tensile and compressive data on aluminum alloy, stainless-steel, and carbon-steel sheet in NACA Technical Note No. 840 indicates that the formula is adequate for most of these materials. The formula does not describe the behavior of alclade sheet, which shows a marked change in slope at low stress. It seems probable that more than three parameters will be necessary to represent such stress-strain curves adequately
Buckling of thin-walled cylinder under axial compression and internal pressure by Hsu Lo( )

2 editions published in 1950 in English and held by 119 WorldCat member libraries worldwide

An investigation was made of a thin-walled cylinder under axial compression and various internal pressures to study the effect of the internal pressure on the compressive buckling stress of the cylinder. A theoretical analysis based on a large-deflection theory was also made. The theoretically predicted increase of compressive buckling stress due to internal pressure agrees fairly well with the experimental results
Shear lag in box beams methods of analysis and experimental investigations by Paul Kuhn( )

4 editions published between 1941 and 1942 in English and held by 118 WorldCat member libraries worldwide

The bending stresses in the covers of box beams or wide-flange beams differ appreciably from the stresses predicted by the ordinary bending theory on account of shear deformation of the flanges. The problem of predicting these differences has become known as the shear-lag problem. The first part of this paper deals with methods of shear-lag analysis suitable for practical use. The second part of the paper describes strain-gage tests made by the NACA to verify the theory. Three tests published by other investigators are also analyzed by the proposed method. The third part of the paper gives numerical examples illustrating the methods of analysis. --
Deformation analysis of wing structures by Paul Kuhn( )

2 editions published in 1947 in English and held by 118 WorldCat member libraries worldwide

The elementary theories of bending and torsion often do not describe the stresses in aircraft shell structures with adequate accuracy; more refined stress theories have therefore have developed over a period of years. Theories of this nature are applied to the problem of calculating the deflections, particularly of wings. Bending as well as torsional deflections are discussed for wings without or with cut-outs. Whenever convenient, the formulas are given in such a form that they yield corrections to be added to the deflections calculated by means of the elementary theories. Examples show that the deflection corrections usually are quite small; very simple approximation formulas are therefore adequate for design purposes when conventional structures uder a reasonably uniform loading are being considered
Critical stress of thin-walled cylinders in torsion by S. B Batdorf( )

3 editions published in 1947 in English and held by 117 WorldCat member libraries worldwide

A theoretical solution is given of the critical stress of thin-walled cylinders loaded in torsion. The results are presented in terms of a few simple formulas and curves which are applicable to a wide range of cylinder dimensions from very short cylinders of large radius to long cylinders of small radius. Theoretical results are found to be in somewhat better agreement with experimental results than previous theoretical work for the same range of cylinder dimensions
The influence of impact velocity on the tensile characteristics of some aircraft metals and alloys by Donald S Clark( )

2 editions published in 1942 in English and held by 116 WorldCat member libraries worldwide

This report deals principally with the results of tension tests on sixteen metals and alloys, most of which are employed extensively in aircraft construction. The tension characteristics are discussed for static conditions and rates of deformation up to about 150 feed per second
Critical combinations of torsion and direct axial stress for thin-walled cylinders by S. B Batdorf( )

2 editions published in 1947 in English and held by 116 WorldCat member libraries worldwide

A theoretical solution is presented for the determination of the combinations of direct axial stress and torsion which cause thin-walled cylinders with either simply supported or clamped edges to buckle. This theoretical solution is used in conjunction with available test data to develop empirical curves and formulas for use in design. Comparisons are made with theoretical and empirical solutions obtained in other investigations
Bending of rectangular plates with large deflections by Chi-teh Wang( )

2 editions published in 1948 in English and held by 116 WorldCat member libraries worldwide

This document presents the solution of Von Karman equations for thin plates with large deflections for special cases of rectangular plates of 1.5 and 2.0 length-width ratios under uniform normal pressure. The boundary conditions approximate panels with riveted edges under normal pressure greater than that of the surrounding panels. Center deflections (to twice the plate thickness), membrane stresses, and extreme-fiber bending stresses are given as functions of the pressure. For small deflections, the results are consistent with those given by Timoshenko
Critical combinations of shear and longitudinal direct stress for long plates with transverse curvature by S. B Batdorf( )

2 editions published in 1947 in English and held by 115 WorldCat member libraries worldwide

A theoretical solution is presented for the buckling stresses of long plates with transverse curvature loaded in shear and longitudinal direct stress. The theoretical critical-stress combinations for plates having either simply supported or clamped edges are given in figures and tables and a comparison is made with a previous theoretical solution for simply supported plates
A Method of calculating the compressive strength of Z-stiffened panels that develop local instability by George L Gallaher( )

2 editions published in 1947 in English and held by 115 WorldCat member libraries worldwide

A method, based on the elastic theory for plate buckling and test results for 24S-T aluminum-alloy Z-stiffened panels, is shown for calculating the compressive strength of Z-stiffened panels that develop local instability. This method can be used to calculate the critical compressive stress above, as well as within, the elastic range. For stresses above three-fourths the compressive yield stress the method can be used for the approximate determination of the average compressive stress at maximum load
Some investigations of the general instability of stiffened metal cylinders. 8 - Stiffened metal cylinders subjected to pure torsion by Louis G Dunn( )

4 editions published in 1947 in English and held by 115 WorldCat member libraries worldwide

An experimental investigation of the general instability of reinforced thin-walled metal cylinders was carried out at the California Institute of Technology. The basic parameters involved were the spacing and sectional properties of stiffening elements, the wall thickness, and the diameter of the cylinder. An analysis of the experimental data led to a suitable parameter for estimating the general-instability stress of reinforced metal cylinders when subjected to pure torsion loading
Plastic buckling of simply supported compressed plates by Richard A Pride( )

2 editions published in 1949 in English and held by 115 WorldCat member libraries worldwide

Tests were made of 14S-T6 aluminum-alloy square tubes to determine the critical compressive stress of simply supported flat plates in the plastic range. Excellent agreement is shown with with Stowell's theory for plastic buckling which is based upon a deformation theory of plasticity, close agreement with two other deformation-type theories of plastic buckling and withthe secant-modulus method, and marked disagreement with a buckling theory based upon a flow theory of plasticity
Nonlinear large-deflection boundary-value problems of rectangular plates by Chi-Teh Wang( )

2 editions published in 1948 in English and held by 115 WorldCat member libraries worldwide

Relaxation and successive approximation methods are used to solve Von Karman's equations as applied to initially flat, rectangular plates with large deflections under either normal pressure or combined normal pressure and side thrust, and several specific cases are analyzed. The general method developed may be applied to bending and combined bending and buckling problems with practically any boundary conditions to any required degree of accuracy or applied to solve the membrane theory of the plate which applies when the deflection is very large in comparison with the thickness of the plate
