This book was released on 2008-07-23 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shells and plates are critical structures in numerous engineering applications. Analysis and design of these structures is of continuing interest to the scienti c and engineering communities. Accurate and conservative assessments of the maximum load carried by a structure, as well as the equilibrium path in both the elastic and inelastic range, are of paramount importance to the engineer. The elastic behavior of shells has been closely investigated, mostly by means of the nite element method. Inelastic analysis however, especially accounting for damage effects, has received much less attention from researchers. In this book, we present a computational model for nite element, elasto-plastic, and damage analysis of thin and thick shells. Formulation of the model proceeds in several stages. First, we develop a theory for thick spherical shells, providing a set of shell constitutive equations. These equations incorporate the effects of transverse shear deformation, initial curvature, and radial stresses. The proposed shell equations are conveniently used in nite element analysis. 0 AsimpleC quadrilateral, doubly curved shell element is developed. By means of a quasi-conforming technique, shear and membrane locking are prevented. The element stiffness matrix is given explicitly, making the formulation computationally ef cient. We represent the elasto-plastic behavior of thick shells and plates by means of the non-layered model, using an Updated Lagrangian method to describe a small-strain geometric non-linearity. For the treatment of material non-linearities, we adopt an Iliushin’s yield function expressed in terms of stress resultants, with isotropic and kinematic hardening rules.

Available in PDF, EPUB and Kindle. Book excerpt: This revised and updated edition of a book first published in 1972 has kept the general features of the first edition but as could be expected after two decades there are also substantial differences. For instance optimal design has been completely deleted as the developments in this field have been so great that it warrants a book in itself. The fundamental concepts based on Drucker's postulate rather than those of Prager's assumptions function have been introduced. Problems of cyclic loading have been given some more extensive treatment, both in the general theory and in applications. General indications and references have been added for reinforced concrete plates and shells. A general presentation of the yield condition for both plates and shells has been included and the section on the influence of axial force in plates has been almost re-written. Finally, a chapter has been added exclusively devoted to the numerical approach to limit load and shake-down load evaluation. Like the previous edition the book is directed towards engineering applications. The theory is rigorously developed and is therefore of great use to engineering students in plastic limit analysis. Furthermore, applications to metal and reinforced concrete plates and shells and to metal disks are treated by both analytical and numerical approaches.

Available in PDF, EPUB and Kindle. Book excerpt: The stress-strain relations developed by the author in previous work for use beyond the elastic range have been simplified and applied to thin plates. Different expressions are given for these relations in the elastic, the elasto-plastic, and the plastic zones which may arise in a thin plate. The stability of plates compressed beyond the elastic range is studied and examples are given of exact and approximate solutions.

Available in PDF, EPUB and Kindle. Book excerpt: A finite element method is described for the large displacement elastic-plastic analysis of plates and shells. The method combines the piecewise linear geometric stiffness matrices with the piecewise linear generalized stress strain relations for an elastic-plastic shell. The method is discussed with special reference to a triangular plate element with membrane stretching and flexure. A quadratic displacement function was used for the in-plane displacements, and a piecewise modified complete cubic displacement function was used for the out-of-plane displacements. This last resulted in a nonconforming element which exhibited good convergence features. The method was implemented on a general purpose computer program. Case studies were made of simply supported square plates under uniform pressure. Studies were also made of axisymmetric shells using an axisymmetric shell element. Reselts for both types of structures were found to agree with available theoretical and experimental results in the literature. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A finite element displacement method is developed for the elasto-plastic analysis of bi-linear strain-hardening orthotropic plates and shells. Two basic approaches in the elasto-plastic analysis, the 'initial stiffness' approach and the 'tangent stiffness' approach are presented and compared. Three separate computer programs have been written; the first two are for the plane stress case. The third program is for the rectangular shallow shells, and it uses elements whose thicknesses are subdivided into equally-spaced layers, each of which is assumed to be in plane stress. (Author).
