Creep Buckling of Plates and Shells


Book Description

A review is presented of the fundamental considerations that enter into the calculation of the buckling of plates and shells whose material deforms in consequence of nonlinear creep. Results are given of analyses that have been carried out for flat plates subjected to edge-wise compression and for circular cylindrical shells subjected to uniform axial compression, to a uniform external pressure and to a constant bending moment. The character of the behavior of these structural elements after buckling is also discussed. (Author).







Nonlinear Analyses of Laminated Plates and Shells with Damage


Book Description

The contents of this book are related to composite mechanics, nonlinear plate and shell mechanics, damage mechanics, elasto-plastic mechanics, visco-elastic mechanics, piezoelectric elastic mechanics and nonlinear dynamics, which embody the combination and integration among solid mechanics, material science and nonlinear science.




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.




Buckling of Structures


Book Description

This volume contains the written texts of the papers presented at a Symposium on Buckling of Structures held at Harvard University in June 1974. This symposium, one of several on various topics sponsored annually by the International Union of Theoretical and Applied Me chanics (IUTAM), was organized by a Scientific Committee consisting of B. Budiansky (Chairman), A. H. Chilver, W. T. Koiter, and A. S. Vol' mir. Participation was by invitation of the Scientific Committee, and specific lecturers were invited to speak in the areas of experimental research, buckling and post-buckling calculations, post-buckling mode interaction, plasticity and creep effects, dynamic buckling, stochastic problems, and design. A total of 29 lectures were delivered, including a general opening lecture by Professor Koiter, and there were 93 reg istered participants from 16 different countries. Financial support for the symposium was provided by IUTAM, in the form of partial travel support for a number of participants, and also by the National Science Foundation, the National Aeronautics and Space Administration, and the Air Force Office of Scientific Re search, for additional travel support and administrative expenses. Meeting facilities and services were efficiently provided by the Science Center of Harvard University, and administrative support was gen erously provided by the Division of Engineering and Applied Physics of Harvard University. The scientific chairman enjoyed the invaluable assistance of his colleagues Professors J. W. Hutchinson and J. L.




Creep Buckling of Plates


Book Description

The effect of creep on the load carrying ability of plates was investigated. The plates were loaded by compressive forces applied in the plane of the plate. It was assumed that the material deforms due to linear elasticity and steady state creep, and creep strain rate is given by the power law. When a fixed uniaxial load is applied to the plate in such a way that the load remains uniformly distributed during the buckling process, the governing equations indicate that a finite time exists after which the lateral deformations of the plate become unbounded. Simple, closed form expressions for this critical time are derived for various values of the creep exponent, and for the case where primary creep plays an important role. (Author).
