Bending of Rectangular Plates With Large Deflections

Description: Note presenting Von Kármán's equations for thin plates with large deflections are solved for the special cases of rectangular plates with ratios of length to width of 1.5 and 2 and loaded by uniform normal pressure.

Bending of Rectangular Plates With Large Deflections

Description: "The solution of Von Karman's fundamental equations for large deflections of plates is presented for the case of a simply supported rectangular plate under combined edge compression and lateral loading. Numerical solutions are given for square plates and for rectangular plates with a width-span ratio of 3:1. The effective widths under edge compression are compared with effective widths according to Von Karman, Bengston, Marguerre, and Cox and with experimental results by Ramberg, Mcpherson, and Levy" (p. 1).

Bending With Large Deflection of a Clamped Rectangular Plate With Length-Width Ratio of 1.5 Under Normal Pressure

Description: "The Von Karman equations for a thin flat plate with large deflections are solved for the special case of a plate with clamped edges having a ratio of length to width of 1.5 and loaded by uniform normal pressure. Center deflections, membrane stresses, and extreme-fiber bending stresses are given as a function of pressure for center deflections up to twice the thickness of the plate. For small deflections the results coincide with those obtained by Hencky from the linear theory" (p. 1).

Investigation of Stress Distribution in Rectangular Plates With Longitudinal Stiffeners Under Axial Compression After Buckling

Torsion and Transverse Bending of Cantilever Plates

Description: "The problem of combined bending and torsion of cantilever plates of variable thickness, such as might be considered for solid thin high-speed airplane or missile wings, is considered in this paper. The deflections of the plate are assumed to vary linearly across the chord; minimization of the potential energy by means of the calculus of variations then leads to two ordinary linear differential equations for the bending deflections and the twist of the plate. Because the cantilever is analyzed as a plate rather than as a beam, the effect of constraint against axial warping in torsion is inherently included" (p. 1).

Resistance of Plates and Pipes at High Reynolds Numbers

Description: It was learned that the law of resistance for high R values does not follow the simple powers, and that the powers, which can be obtained approximately for the velocity distribution, gradually change. Since, moreover, very important investigations have recently been made on the resistance of plates at very high R values, it seemed of interest to apply the above line of reasoning to the new general law of resistance. For this purpose, the resistance and velocity distribution along the plate must always be equal to the values of the pipe flow at the corresponding Reynolds number.

The High-Speed Planing Characteristics of a Rectangular Flat Plate Over a Wide Range of Trim and Wetted Length

Description: Note presenting an investigation of the principal high-speed planing characteristics for a prismatic surface with an angle of dead rise of 0 degrees determined over a wide range of planing variables. Wetted length, resistance, center-of-pressure location, and draft were determined at speed coefficients ranging up to 25.0, beam loadings up to 87.3, and trims up to 30 degrees.

Effect of Small Deviations From Flatness on Effective Width and Buckling of Plates in Compression

Description: Note presenting a theoretical investigation undertaken to evaluate the effect of small deviations from flatness on the behavior of simply supported square plates under compression, it being assumed that the proportional limit is not exceeded. Results regarding the growth of buckles with increase in load, effective width of plate, experimentally defined buckling or critical stress, critical stress and postbuckling behavior of the plate, and the Southwell plot method of predicting theoretical critical stress are provided.

Critical Combinations of Shear and Longitudinal Direct Stress for Long Plates With Transverse Curvature

Description: Note presenting a theoretical solution for the buckling stresses of long plates with transverse curvature loaded in shear and longitudinal direct stress. The theoretical critical-stress combinations for plates with either simply supported or clamped edges are given in figures and tables and a comparison is made with previous theoretical solutions.

Flow Phenomena on Plates and Airfoils of Short Span

Description: "Investigations on the flow phenomena at plates and cambered models were carried out with the aid of force measurements, some pressure distribution measurements, and photographic observation. The experimental methods are described and the results given. Section III of this work gives a comprehensive account of the results and enables us to see how nearly the lift line and lift surface theories agree with the experimental results" (p. 1).

Buckling Stresses of Simply Supported Rectangular Flat Plates in Shear

Description: "The present paper evaluates the shear buckling stresses of rectangular flat plates with simply supported edges more accurately than previous work on this problem. Both symmetric (odd number of buckles) and antisymmetric (even number of buckles) patterns were considered. A curve is presented from which the critical stresses may be obtained when the dimensions of the plate are known" (p. 1).

Minimum-Weight Design of Simply Supported Transversely Stiffened Plates Under Compression

Description: Note presenting an investigation of the weight of a simply supported transversely stiffened compression panel subjected to a given buckling load as a function of the stiffener spacing, plate thickness, and the geometry of the stiffener cross section. Results indicate that there are particular combinations of stiffener spacing and plate thickness, dependent on the geometrical properties of the stiffener cross section, for which the panel weight is a minimum.

Investigation of the Influence of the Boundaries of a High-Speed Free Water Jet on the Planing Lift of a Flat Plate

Description: Memorandum presenting an investigation to determine the influence of the boundaries of a high-speed free water jet on the planing lift of a flat plate operating on the surface of the jet. No appreciable influence of speed on the planing lift coefficient for speeds from 50 to 200 feet per second was observed. Results also indicated that the parameters determining the jet size required for a given test condition have not been defined by these brief tests.

Deflections of a Simply Supported Rectangular Sandwich Plate Subjected to Transverse Loads

Description: "The differential equations of the bending of sandwich plates were integrated to obtain the deflections when the four edges of the plate are simply supported and the loading consists of either a uniformly distributed transverse load or a concentrated load applied at the center of the panel. The deflection patterns are shown in diagrams and the maximum deflection of the plate is presented in a number of graphs" (p. 1).

Buckling Stresses of Clamped Rectangular Flat Plates in Shear

Description: "By consideration of antisymmetrical, as well as symmetrical, buckling configurations, the theoretical shear buckling stresses of clamped rectangular flat plates are evaluated more correctly than in previous work. The results given, which represent the average of upper- and lower-limit solutions obtained b the Lagrangian multiplier method, are within 1 1/4 percen of true buckling stresses" (p. 1).

Buckling in Shear of Continuous Flat Plates

Description: "As basic information for the design of thin-web spars, the theoretical shear buckling stress is presented for an infinitely long, clamped plate divided into square panels by rigid intermediate supports. In addition, results are given for the shear buckling stress of a plate of infinite length and width having intermediate rigid supports that form an array of square panels. The results indicate the fallacy of the usually made assumption that each panel buckles in shear as if it were simply supported along the intermediate supports" (p. 1).

A Theory for the Elastic Deflections of Plates Integrally Stiffened on One Side

Description: Note presenting an elastic-deflection theory for anisotropic plates which exhibit coupling between bending and stretching. The theory provides a basis for analyzing plates integrally stiffened on one side. Example calculations show that in the case of a simply supported square plate loaded in compression and with equal flexural stiffnesses in the principal directions, coupling may significantly lower the in-plane compressive load at which deflections grow rapidly.
