This book was released on 1972 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The method of least square point matching is employed in the analysis of a shallow, circular cylindrical shell with a cutout. The cylinder may be infinite or semi-infinite, and the cutout is either circular or elliptic. For the ellipse the major axis can be oriented either parallel or perpendicular to the generator. In particular, two examples are presented: an infinite cylinder subjected to uniform axial tension, and a semi-infinite cylinder loaded at its edge by either a uniform bending moment or a transverse shear force. In both cases the minor axis of the elliptic cutout is parallel to the generator. The boundary of the perforation is free of tractions and supports. Numerical results are presented and show the effects of variations in: the hole size to cylinder curvature ratio; the eccentricity of the cutout; and for semi-infinite cylinders, the distance from the cutout to the edge.

Available in PDF, EPUB and Kindle. Book excerpt: A class of problems concerned with the determination of the stress field in a circular cylindrical shell with a circular cutout is investigated. Specifically, the following three cases are treated: (a) the shell subjected to a uniformly distributed bending moment around the cutout; (b) the shell subjected to a uniform axial tensile load with a stress-free cutout; and (c) an internally pressurized shell with a uniform transverse shear at the edge of the cutout. By superposition of the results for these cases one may obtain the solution of several other technically important problems. The method employs solution of the Donnell theory of thin shells satisfying the boundary conditions at the circular cutout in a collocation sense. The accuracy and the domain of applicability of the method is demonstrated and discussed. A forthcoming report will present extensive computer calculations for these cases. (Author).

This book was released on 1963 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a recent report by Naghdi and Eringen (G.T.C. Technical Report No. 3-2, 'Stress Analysis of a Circular Cylindrical Shell with Circular Cutout, ' January 1963) (AD-640 558), a theoretical analysis of an infinitely long circular cylindrical shell with a circular cutout is presented. Specific results are obtained for three particular cases in which the shell is subjected to: Case I.A uniformly distributed bending moment around the edge of the cutout. (Pending Moment Case) Case II. A uniform longitudinal tensils load with the edge of the cutout stress-free. (Extension Case) Case III. A uniform internal pressure with a uniform transverse shear at the edge of the cutout. (Internal Pressure Case) The analytical results of the cited Technical Report 3-2 are used in the detailed calculations undertaken for the present report. The state of stress for each of the three cases above is determined for a variety of cylindrical shells having different material and geometry properties. Stress concentration factors are also calculated for Cases II and III. The present report includes a summary of significant results presented in Technical Report 3-2. To avoid excessive duplication, only pertinent expressions are repeated here, except those which are too lengthy to reproduce. Therefore, for these long expressions, reference has to be made to Technical Report 3-2. In addition there is presented a discussion on stress concentration for a combined state of stress not included in Technical Report 3-2. The calculated numerical results are presented and discussed for each of the three cases described above. The application of these data are indicated.

This book was released on 1965 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains the derivation of the equations for an orthotropic circular cylindrical shell. The orthotropic material properties of the shell represent the effects of a large number of radial holes penetrating the shell surface in rectangular patterns. The general equations for the orthotropic shell are obtained and are then reduced to a rotationally symmetric form for the case when the penetration patterns extend completely around the shell and the shell is subjected to hydrostatic pressure. These axisymmetric orthotropic cylindrical shell equations are solved as the first and simplest class of solutions obtainable. The orthotropic axisymmetric shell solutions yield the stresses directly which may then be considered average stress values in our idealized structure. Consequently, the investigation later concerns itself with obtaining a method for calculating the peak stress values which occur in the actual penetrated shell. (Author).

This book was released on 1964 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains the results of the first phase of a three phase program. In this first phase the definitions for the effective orthotropic stiffness coefficients are formulated in terms of the geometric and elastic material properties for a right circular cylindrical shell penetrated by a large number of radial circular holes. The effective stiffness coefficients are developed in a manner quite similar to that used for determining the coefficients for a flat perforated plate. Phases two and three will contain the development of the shell differential equations with solutions and the study of stress distributions respectively. A fourth phase may be necessary in which the same complete process will be repeated for a large number of circular holes of a triangular pattern in the circular cylinder. (Author).
