Bonanni and published by . This book was released on 1994 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of thick-section laminated composite materials and structures have suggested that there is a need for three-dimensional (3-D) structural analysis methods which include the nonlinear material response of the constituents. The work described in this paper integrates a 3-D micromechanics-based nonlinear constitutive model for laminated composite materials into 3-D structural analyses performed with the ABAQUS general purpose finite element code. The nonlinear model and its incorporation into ABAQUS are described. The method is demonstrated through 3-D stability analyses of thick, unstiffened AS4/3501-6 carbon/epoxy circular cylinders under external hydrostatic pressure. The results of two-dimensional (2-D) shell finite element analyses of these cylinders are also presented for comparison. The cylinders analyzed are geometrically identical and are subjected to the same loading and boundary conditions. Five different ply layups are considered, including cross-ply, quasi-isotropic, and [±45°]. Modeling the nonlinear material response is found to reduce the predicted cylinder collapse load by up to 50% when layers oriented at ±45° to the cylinder axis are present in the laminate. The role of material nonlinearity in the plane of the laminate versus through-thickness nonlinearity is discussed for the cylinders analyzed.

This book was released on 2013-07-03 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capability to predict the nonlinear response of beams, plates and shells when subjected to thermal and mechanical loads is of prime interest to structural analysis. In fact, many structures are subjected to high load levels that may result in nonlinear load-deflection relationships due to large deformations. One of the important problems deserving special attention is the study of their nonlinear response to large deflection, postbuckling and nonlinear vibration. A two-step perturbation method is firstly proposed by Shen and Zhang (1988) for postbuckling analysis of isotropic plates. This approach gives parametrical analytical expressions of the variables in the postbuckling range and has been generalized to other plate postbuckling situations. This approach is then successfully used in solving many nonlinear bending, postbuckling, and nonlinear vibration problems of composite laminated plates and shells, in particular for some difficult tasks, for example, shear deformable plates with four free edges resting on elastic foundations, contact postbuckling of laminated plates and shells, nonlinear vibration of anisotropic cylindrical shells. This approach may be found its more extensive applications in nonlinear analysis of nano-scale structures. Concentrates on three types of nonlinear analyses: vibration, bending and postbuckling Presents not only the theoretical aspect of the techniques, but also engineering applications of the method A Two-Step Perturbation Method in Nonlinear Analysis of Beams, Plates and Shells is an original and unique technique devoted entirely to solve geometrically nonlinear problems of beams, plates and shells. It is ideal for academics, researchers and postgraduates in mechanical engineering, civil engineering and aeronautical engineering.

This book was released on 2014-07-08 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the nonlinear behaviour of thin-wall shells (single- and multilayered with delamination areas) under various uniform and non-uniform loadings. The dependence of critical (buckling) load upon load variability is revealed to be highly non-monotonous, showing minima when load variability is close to the eigenmode variabilities of solution branching points of the respective nonlinear boundary problem. A novel numerical approach is employed to analyze branching points and to build primary, secondary, and tertiary bifurcation paths of the nonlinear boundary problem for the case of uniform loading. The load levels of singular points belonging to the paths are considered to be critical load estimates for the case of non-uniform loadings.
Download or read book Analysis of the Nonlinear Large Deformation Behavior of Composite Cylindrical Shells written by George J. Simitses and published by . This book was released on 1983 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The governing equations for the nonlinear analysis of imperfect, stiffened, laminated, circular, cylindrical, thin shells, subjected to uniform axial compression and torsion, and supported in various ways, are derived and presented. Two types of formulations have been developed; one (w, F-Formulation) is based Donnell-type nonlinear kinematic relations; and the other (u, v, w - formulation) is based on Sanders' -type of nonlinear kinematic relations (small strains, moderate rotations about in-plane axes). A solution methodology is developed and presented. Numerical results are generated for certain special geometries, and these serve as bench marks for the solution scheme. Parametric studies are performed for composite cylinders. The scope of these studies is to assess the effect of geometric imperfections lamina stacking, and length of radius ratio. The solution scheme is also tested by comparing theoretical predictions (critical loads based on the developed methodology) to experimentally obtained results.

Download or read book Non Classical Problems in the Theory of Elastic Stability written by Isaac Elishakoff and published by Cambridge University Press. This book was released on 2001-01-29 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a structure is put under an increasing compressive load, it becomes unstable and buckling occurs. Buckling is a particularly significant concern in designing shell structures such as aircraft, automobiles, ships, or bridges. This book discusses stability analysis and buckling problems and offers practical tools for dealing with uncertainties that exist in real systems. The techniques are based on two complementary theories which are developed in the text. First, the probabilistic theory of stability is presented, with particular emphasis on reliability. Both theoretical and computational issues are discussed. Secondly, the authors present the alternative to probability based on the notion of 'anti-optimization', a theory that is valid when the necessary information for probabilistic analysis is absent, that is, when only scant data are available. Design engineers, researchers, and graduate students in aerospace, mechanical, marine, and civil engineering who are concerned with issues of structural integrity will find this book a useful reference source.
