This book was released on 1969 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey is first made of finite element analysis with nonlinear elastic-plastic and/or geometric behavior. Incremental stiffness matrices are then developed for the small strain large displacement analysis of combined nonlinear problems. The element stiffness matrices are obtained from the principle of virtual work. The theory is demonstrated with reference to a three-dimensional constant stress tetrahedron element. A general purpose finite element program for combined nonlinear analysis is then described. Case studies, using the program, examine the behavior of axisymmetric shells, flat plates and structures in plane stress. (Author).

Download or read book A Koiter type Method for Finite Element Analysis of Nonlinear Structural Behavior written by Raphael T. Haftka and published by . This book was released on 1970 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Koiter's method for the asymptotic analysis of post-buckling behavior is reformulted in finite element notation for application to structures idealized by finite element models. Koiter's method is herein adapted to a general class of structures exhibiting the common snap-through (limit point) type of buckling. This is referred to as the Modified Structure method. It is accomplished by modification of the actual energy functional to create a hypothetical modified structure having a strictly linear pre-buckling path along which buckling must be of the bifurcation type. The analysis of the actual structure is then accomplished by application of Koiter's method through consideration of the actual structure as an imperfect version of the modified structure. The effects of pre-buckling nonlinearity are approximated asymptotically. The use of the Modified Structure method in conjunction with direct methods of nonlinear analysis is examined. A highly accurate finite element representation is employed in presenting a comprehensive numerical evaluation of the Modified Structure method of analysis on the basis of a number of planar frame problems.

Download or read book The Finite Element Analysis of Shells Fundamentals written by Dominique Chapelle and published by Springer Science & Business Media. This book was released on 2010-11-09 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents 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. In this Second Edition the authors give new developments in the field and - to make the book more complete - more explanations throughout the text, an enlarged section on general variational formulations and new sections on 3D-shell models, dynamic analyses, and triangular elements. The analysis of shells represents one of the most challenging fields in all of mechanics, and encompasses various fundamental and generally applicable components. Specifically, the material presented in this book regarding geometric descriptions, tensors and mixed variational formulations is fundamental and widely applicable also in other areas of mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: The powder forming process is an extremely effective method of manufacturing structural metal components with high-dimensional accuracy on a mass production basis. The process is applicable to nearly all industry sectors. It offers competitive engineering solutions in terms of technical performance and manufacturing costs. For these reasons, powder metallurgy is developing faster than other metal forming technology. Computational Plasticity in Powder Forming Proceses takes a specific look at the application of computer-aided engineering in modern powder forming technologies, with particular attention given to the Finite Element Method (FEM). FEM analysis provides detailed information on conditions within the processed material, which is often more complete than can be obtained even from elaborate physical experiments, and the numerical simulation makes it possible to examine a range of designs, or operating conditions economically. * Describes the mechanical behavior of powder materials using classical and modern constitutive theories.* Devoted to the application of adaptive FEM strategy in the analysis of powder forming processes.* 2D and 3D numerical modeling of powder forming processes are presented, using advanced plasticity models.
