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).

Available in PDF, EPUB and Kindle. Book excerpt: The report contains a summary of the work done under a continuing research contract given to Applied Technology Associates in the field of pressure vessel design. In particular is developed the theoretical solution for the distribution of stresses in a perforated cylindrical shell. These calculations have been reduced to computer codes and are given in the appendix of the report. In addition to the computer codes developed for the effective elastic constants, the report contains a code for the analysis of a circular cylindrical shell whose surface is penetrated only over a portion. Thus the 'equivalent' elastic constants obtained can be used within the shell theory developed in the report to describe the deflections and stresses in a partially perforated shell. (Author).

This book was released on 1968 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The method presented here is based on the assumption that a set of 'equivalent' elastic constants can be developed for a perforated shell and that these 'equivalent' elastic constants can be used within the classical shell theory to obtain the average deflections and stresses in the perforated shell. The development of the 'equivalent' elastic constants is achieved by comparing the strain energy of an idealized typical element of the perforated shell under stress to a similarly stressed, isotropic, unperforated cylindrical shell element. In the idealization of the element for the perforated shell the beam ligaments and a central inner triangular portion are considered to simulate the total strain energy density. The procedure of including the additional central element is similar to that developed for the square pattern of penetrations in a plate. The final comparison of the two strain energy densities for the idealized element and the isotropic shell element is then performed in a manner similar to that developed by Horvay and Malkin for perforated plate elements. The 'equivalent' elastic constants so determined can then be used in the generalized cylindrical shell equations to obtain a final solution for the deflections and stresses. Author).

Download or read book Analysis of a Perforated Cylindrical Shell Part Ii Derivation of Equations for the Stress Analysis of a Fully Penetrated Shell written by J. B. Mahoney and published by . 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 2017-12-18 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Stresses in a Perforated Cylindrical Shell In this paper we study the deformations of perforated cylindrical elastic shells that are subjected to surface and boundary forces. The presence of a hole in the shell's wall significantly alters the distribution and magnitudes of the stresses. Approximate procedures, which are restricted in their applicability, have been proposed by various authors [1-6] to determine these stresses. The paper by Savin [h] also contains a general discussion of shell cutout problems and references to previous work.
