This book was released on 1968 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discrete-element displacement method is developed for the static or dynamic analysis of core-stiffened shells of revolution for asymmetric mechanical loading. The discrete-element mass, stiffness, and consistent nodal force matrices are developed. The solution of the static problem for both restrained and unrestrained structures is discussed. Several example problems are solved to illustrate the usefulness of the method. A FORTRAN IV computer program for performing the static analysis is given. (Author).

This book was released on 1968 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The methods of discrete-element analysis are applied to the solution of arbitrary shells of revolution having two layers joined by a soft bond; the shell is idealized as a series of frusta with curved meridians, joined at the nodal circles. The displacement assumptions for the soft-bonded two-layer discrete element permit the sliding of the upper and lower layers with respect to each other, but the normal displacement of the upper and lower layers is assumed to be the same. The asymmetric loading problem is handled through a Fourier expansion of the loads and displacements. Numerical results for various shells of revolution for both axisymmetric and asymmetric mechanical and thermal loadings have been obtained to exercise various features and options of the computer program SABOR 5. These results are compared with existing solutions and good correlation is found. The SABOR 5 program can be used for the static analysis of variable-thickness shells of revolution composed of soft-bonded double-layers, single layers, or branched-shell combinations thereof, while accounting for isotropic or general skew orthotropic material properties and for arbitrary (axisymmetric and/or asymmetric) mechanical and/or thermal loads.

Available in PDF, EPUB and Kindle. Book excerpt: A discrete element analysis method for predicting the nonlinear response of thin elastic shells is presented. The displacement patterns for a shell element, the edges of which must be parallel to orthogonal curvilinear coordinates, are expressed in terms of products of one-dimensional Hermite interpolation polynomials and undetermined nodal displacement parameters. Geometric admissibility of the displacement state of an assemblage of these discrete elements is conveniently satisfied. Special treatment is given to the particular cases of flat rectangular plate and circular cylindrical shell discrete elements. The use of a potential energy principle permits the incorporation of geometric nonlinearity, thus providing the capability for predicting finite displacements and post-buckling behavior. Numerical solutions are obtained by direct minimization of the total discretized potential energy. Several numerical examples, both linear and nonlinear, which indicate the effectiveness of the analysis are considered. The applicability of this discrete element analysis method to predicting the elastic post-buckling behavior of integrally stiffened shells is provided by the assumed element displacement patterns.

Download or read book Finite Element Bibliography written by Gerard De Vries and published by Springer. This book was released on 1976-12 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thjs bibliography had its inception in 1967, when the compilers first attempted a comprehensive cov erage of the finite element literature using both manual and computer-based retrieval. Initially, the data base was stored on a card index, but this was subsequently transferred to punched cards and magnetic tape. Computer processing was adopted at an early stage to derive the three index formats from the data base. Over the subsequent years, several versions of the bibliography were produced, with two of these being made available in a report form to other researchers. From the widespread interest in these documents, it became evident that there was a need for a commercially-available comprehensive bibliography in this area. A major effort was undertaken to revise, update, and extend the data base, resulting in this present volume. The bibliography covers the period 1956-1975 primarily, although some earlier publications of histori cal interest are included. The citations are not restricted to the English language and documents are listed in many languages and from diverse places of origin. All publication formats were accepted, so that references will be found to books, monographs, journal papers and articles, theses, dissertations, reports, surveys, and the like.

This book was released on 2013-03-09 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a modern continuum mechanics and mathematical framework to study shell physical behaviors, and to formulate and evaluate finite element procedures. With a view towards the synergy that results from physical and mathematical understanding, the book focuses on the fundamentals of shell theories, their mathematical bases and finite element discretizations. The complexity of the physical behaviors of shells is analysed, and the difficulties to obtain uniformly optimal finite element procedures are identified and studied. Some modern finite element methods are presented for linear and nonlinear analyses. A state of the art monograph by leading experts.

Yeghiayan and published by . This book was released on 1970 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discrete-element static structural analysis program SABOR 5 has been applied to analyze several structural configurations consisting of single-layer and/or bonded double-layer shell-of-revolution structures. This experience resulted in various improvements to the SABOR 5 program. The effects on SABOR 5 predictions of the structural behavior of typical configurations, resulting from choosing a variety of alternate plausible discrete-element modelings, particularly for structural-joint and/or constraint regions of the structure where several adjacent layers exist, is investigated and illustrated. Also studied is the sensitivity of the predicted behavior of statically-loaded typical shell configurations to various types of simplified structural discrete-element modelings and support-point modelings, selected structural thickening near support points, variations in material properties of isotropic shell layers and bonds and/or of orthotropic shell layers, and skew orientation of orthotropic shell-layer material, all in the context of applying the SABOR 5 program.
