Strength tests of thinwalled duralumin cylinders in pure bending by
Eugene E Lundquist(
Book
)
1 edition published in 1933 in English and held by 6 WorldCat member libraries worldwide
This report is the third of a series presenting the results of strength tests on thinwalled cylinders and truncated cones of circular and elliptic section; it includes the results obtained from pure bending tests on 58 thinwalled duralumin cylinders of circular section with ends clamped to rigid bulkheads. The tests show that the stress on the extreme fiber at failure as calculated by the ordinary theory of bending is from 30 to 80 percent greater than the compressive stress at failure for thinwalled cylinders in compression. The tests also showe that length/radius ratio has no consistent effect upon the bending strength and that the size of the wrinkles that form on the compression half of a cylinder in bending is approximately equal to the size of the wrinkles that form in the complete circumference of a cylinder of the same dimensions in compression

A Method of estimating the critical buckling load for structural members by
Eugene E Lundquist(
Book
)
2 editions published between 1939 and 1940 in English and held by 6 WorldCat member libraries worldwide
The solutions of six simple problems are included to illustrate the application of the method of estimating critical loads and to reveal certain characteristics of the method that should be known by the practical engineer using it. Four of these problems are concerned with members that lie in the elastic, or longcolumn, range. The other two problems are concerned with memberes that lie in the shortcolumn range

Generalized analysis of experimental observations in problems of elastic stability by
Eugene E Lundquist(
Book
)
4 editions published in 1938 in English and held by 6 WorldCat member libraries worldwide
A generalized method of analyzing experimental observations in problems of elastic stability is presented in which the initial readings of load and deflection may be taken at any load less than the critical load. This analysis is an extension of a method published by Southwell in 1932, in which it was assumed that the intial readings are taken at zero load

Local instability of symmetrical rectangular tubes under axial compression by
Eugene E Lundquist(
Book
)
3 editions published between 1938 and 1939 in English and held by 5 WorldCat member libraries worldwide
A chart is presented for the coefficient in the formula for the critical compressive stress at which crosssectional distortion begins in a thinwall tube of rectangular section symmetrical about its two principal axes. The energy method of Timoshenko was used in the theoretical calculations required for the construction of the chart. The deflection equation used in this method was selected to give good accuracy. The exact values given by solutino of the differential equation were calculated for a number of cases and it was found that the energy solution was correct to within a fraction of 1 percent

Book
)
2 editions published in 1932 in English and held by 5 WorldCat member libraries worldwide
This report is the first in a series presenting the results of strength tests on thinwalled cylinders and truncated cones of circular and elliptical section; it comprises the results obtained to date from torsion (pure shear) tests of 65 thinwalled duralumin cylinders of circular section with ends clamped to rigid bulkheads.

Column and plate compressive strengths of aircraft structural materials 24ST aluminumalloy sheet by
Eugene E Lundquist(
Book
)
4 editions published in 1945 in English and held by 3 WorldCat member libraries worldwide
Column and plate compressive strengths of 24ST aluminumalloy sheet were determined both within and beyond the elastic range from tests of thinstrip columns and from localinstability tests of formed Z and channelsection columns. These tests are the first of a series in an extensive research investigation to provide data on the structural strength of various aircraft materials. The results, which are presented in the form of curves and charts that may be used in the design and analysis of aircraft structures, superseded preliminary results published previously

Extended tables of stiffness and carryover factor for structural members under axial load by
Eugene E Lundquist(
Book
)
3 editions published in 1944 in English and held by 2 WorldCat member libraries worldwide
The tables of stiffness and carryover factor that were presented in NACA Technical Note No. 652 have been extended to include the stiffness of a member with the far and subjected to a moment equal and opposite to the moment applied at the near end. These tables are of use in solving problems in the stability of structural members under axial load of moment distribution when the effects of axial load in the members are considered. The values presented are for structural members in which the cross section and the axial load do not vary along the length of the member. The interval between successive values of the argument is small enough to make interpolation unnecessary in engineering calculations

A long column continuous over three supports was tested to determine its critical load when the center support was given varying amounts of initial displacement. During each test the middle support was hinged so as to be free to move parallel to the column axis during buckling
