Seven New White-winged Doves from Mexico, Central America, and Southwestern United States

Seven New White-winged Doves from Mexico, Central America, and Southwestern United States

Date: May 1968
Creator: Saunders, George B.
Description: Seven new subspecies of the white-winged dove (Zenaida asiatica) are described. The patterns of these recoveries are an invaluable aid to understanding racial distribution of this species. The extent of migration that breed in Central America is not yet adequately known. The range of the doves extends as far north as the southwestern United States.

Shape of initial portion of boundary of supersonic axisymmetric free jets at large jet pressure ratios

Shape of initial portion of boundary of supersonic axisymmetric free jets at large jet pressure ratios

Date: January 1, 1958
Creator: Love, Eugene S & Lee, Louise P
Description: Calculations have been made of the initial portion of the boundary of axisymmetric free jets exhausting at large pressure ratios from a conically divergent nozzle having a jet exit Mach number of 2.5 and a semidivergence angle of 15 degrees. The results of the calculations indicate the size and shape of the jet to be expected at large pressure ratios, the effects of ratio of specific heats, and the large initial inclinations of the boundary that are likely to be encountered by hypersonic vehicles at high altitude.

Shear Lag in a Plywood Sheet-Stringer Combination Used for the Chord Member of a Box Beam

Shear Lag in a Plywood Sheet-Stringer Combination Used for the Chord Member of a Box Beam

Date: March 1, 1948
Creator: Borsari, Palamede & Yu, Ai-Ting
Description: Theoretical and experimental investigations were made of the distribution of strains in a plywood sheet-stringer combination used as the chord member of a box beam acted upon by bending loads. The theoretical solution was obtained with the help of the principle of minimum potential energy and certain simplifying assumptions. Strain measurements were made on a build-up box beam by means of electrical-resistance strain gages connected with strain indicators. A very satisfactory agreement between the theoretical and experimental strains was obtained.

Shear lag in box beams methods of analysis and experimental investigations

Shear lag in box beams methods of analysis and experimental investigations

Date: January 1, 1942
Creator: Kuhn, Paul & Chiarito, Patrick T
Description: 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. An appendix gives comparisons with other methods, particularly with the method of Ebner and Koller.

Shear lag in corrugated sheets used for the chord member of a box beam

Shear lag in corrugated sheets used for the chord member of a box beam

Date: January 1, 1941
Creator: Newell, Joseph S & Reissner, Eric
Description: The problem of the distribution of normal stress across a wide corrugated sheet used as the chord of a box-beam-like structure is investigated theoretically and experimentally. Expressions are developed giving the stress distribution in beams, symmetrical or unsymmetrical, about a plane passed spanwise through the center of the sheet. The experiments were arranged to insure bending without torsion and surveys of the normal stresses were made by means of mechanical and electrical strain gages. The experimental data showed very good agreement with the new b of the theoretical curves, especially at the highly stressed sections, for both the symmetrical and unsymmetrical beams. Several suggestions for future research are included.

Shear strength at 75 F to 500 F of fourteen adhesives used to bond a glass-fabric-reinforced phenolic resin laminate to steel

Shear strength at 75 F to 500 F of fourteen adhesives used to bond a glass-fabric-reinforced phenolic resin laminate to steel

Date: December 1, 1956
Creator: Davidson, John R
Description: Fourteen adhesives used to bond a glass-fabric-reinforced phenolic resin laminate to steel were tested in order to determine their shear strengths at temperatures from 75 F to 500 F. Fabrication methods were varied to evaluate the effect of placing cloth between the facing surfaces to maintain a uniform bond-line thickness. One glass-fabric supported phenolic adhesive was found to have a shear strength of 3,400 psi at 300 F and over 1,000 psi at 500 F. Strength and fabrication data are tabulated for all adhesives tested.

Shearing effectiveness of integral stiffening

Shearing effectiveness of integral stiffening

Date: June 1, 1955
Creator: Crawford, Robert F & Libove, Charles
Description: Values of coefficients for defining the effectiveness of integral stiffeners in resisting shear deformations of the plate of which they are an integral part are presented for a variety of proportions of rectangular stiffeners with circular fillets. Formulas are given in which these coefficients may be employed to calculate the elastic constants associated with the twisting and shearing of integrally stiffened plates. The size of fillet radius is shown to contribute appreciably to the degree of penetration of the stresses from the skin into the stiffener.
