Buckling and Post Buckling Structures


Book Description

This book provides an in-depth treatment of the study of the stability of engineering structures. Contributions from internationally recognized leaders in the field ensure a wide coverage of engineering disciplines in which structural stability is of importance, in particular the analytical and numerical modelling of structural stability applied to aeronautical, civil, marine and offshore structures. The results from a number of comprehensive experimental test programs are also presented, thus enhancing our understanding of stability phenomena as well as validating the analytical and computational solution schemes presented. A variety of structural materials are investigated with special emphasis on carbon-fibre composites, which are being increasingly utilized in weight-critical structures. Instabilities at the meso- and micro-scales are also discussed. This book will be particularly relevant to professional engineers, graduate students and researchers interested in structural stability.







Postbuckling Behavior Of Plates And Shells


Book Description

As an expert in structure and stress analysis, the author has written extensively on functionally graded materials (FGMs), nonlinear vibration and dynamic response of functionally graded material plates in thermal environments, buckling and postbuckling analysis of single-walled carbon nanotubes in thermal environments. This book provides a comprehensive overview of the author's works which include significant contributions to the postbuckling behavior of plates and shells under different loading and environmental conditions.This book comprises eight chapters. Each chapter contains adequate introductory material so that an engineering graduate who is familiar with basic understanding of plates and shells will be able to follow it.




Design and Analysis of Composite Structures


Book Description

Design and Analysis of Composite Structures enables graduate students and engineers to generate meaningful and robust designs of complex composite structures. Combining analysis and design methods for structural components, the book begins with simple topics such as skins and stiffeners and progresses through to entire components of fuselages and wings. Starting with basic mathematical derivation followed by simplifications used in real-world design, Design and Analysis of Composite Structures presents the level of accuracy and range of applicability of each method. Examples taken from actual applications are worked out in detail to show how the concepts are applied, solving the same design problem with different methods based on different drivers (e.g. cost or weight) to show how the final configuration changes as the requirements and approach change. Provides a toolkit of analysis and design methods to most situations encountered in practice, as well as analytical frameworks and the means to solving them for tackling less frequent problems. Presents solutions applicable to optimization schemes without having to run finite element models at each iteration, speeding up the design process and allowing examination of several more alternatives than traditional approaches. Includes guidelines showing how decisions based on manufacturing considerations affect weight and how weight optimization may adversely affect the cost. Accompanied by a website at www.wiley.com/go/kassapoglou hosting lecture slides and solutions to the exercises for instructors.




Buckling and Postbuckling of Laminated Composite Plates with Ply Dropoffs


Book Description

An experimental and analytical investigation was conducted on the buckling and postbuckling behavior of laminated graphite/epoxy plates with ply dropoffs under uniaxial compression. Three types of plates were considered: ply dropoff plates with one or more internal plies terminated along a centerline perpendicular to the loading, flat plates to provide the baseline behavior, and angle change plates where the fiber angle of several plies changes abruptly along the centerline. This latter case isolates the change in material properties without the geometric eccentricities present in ply dropoff plates. An analysis method using a "superelement" formulated with a Rayleigh-Ritz assumed deflection model was developed and utilized to predict the linear buckling response of the plates. Both the experimental and analytical results show that ply dropoffs have a marked effect on plate buckling and postbuckling behavior. In contrast to basic flat plates, plates with ply dropoffs exhibit complex deflection shapes that cannot be characterized by simple modes. The buckling load of these plates was related to the ratio of the longitudinal bending stiffness of the dropped and undropped section of the plates and was bounded by the buckling loads of the flat plates with the layup configurations of the two individual sections. The angle change plates exhibited much of the same behavior seen in the ply dropoff plates but indicated that the change in the other bending stiffnesses can also have an important effect on the buckling behavior.




Handbook of Thin Plate Buckling and Postbuckling


Book Description

Stop searching through the endless amount of literature to find the most recent information on plate buckling. The authors of Handbook of Thin Plate Buckling and Post Buckling have already done the work for you. Detailed and clearly written, the book contains a comprehensive, up-to-date treatment of the buckling and postbuckling behavior of perfect and imperfect thin plates. The authors study, in detail and with specific solved examples, the essential factors that influence critical buckling loads, initial mode shapes, and postbuckling behavior for thin plates. Through their analysis of rectangular, circular, and annular plates, they present valuable information, some of which has never before been published in book form. Such topics include hygrothermal buckling, viscoelastic and plastic buckling, and buckling of various thickness plates. With this important collection, the Handbook of Thin Plate Buckling and Post Buckling provides you with a one-stop source of current research findings.
