Book Description
An analysis of long simply-supported rectangular plates with straight unloaded edges uniformly shortened beyond the elastic instability points into the plastic range was undertaken. The inclusion of wavelength effects is shown to be a significant factor in establishing maximum strength criteria for postbuckled plates. The present results are shown to be in excellent agreement with experiment and serve to explain the reason for the absence of clearly-defined maximum load criteria for postbuckled square plates. In addition, the analysis results offer a plausible explanation for the increased maximum strength performance obtained with several tests on beryllium plates considered to be simply-supported, when compared with an essentially material-independent maximum strength criterion established for plates constructed of materials which possess relatively high biaxial ductility. (Author).

Book Description
The postbuckling and maximum strength analyses of uniformly shortened, simply supported rectangular plates with straight unloaded edges are obtained by employing Reissner's variational principle in conjunction with a deformation theory of plasticity. The results are compared to (1) experimental data for a rectangular plate in which the test conditions basically reflect the boundary conditions specified in the present analyses, and (2) a potential energy solution that correlates well with experiment, but in which the effect of waveform change on the average stress carried by the plate is accounted for only in a gross manner and the effect of small local unloading is neglected. Good agreement with experiment establishes confidence in the new approach and indicates that the simplified technique utilized in the potential energy solution to compensate for waveform changes may be employed for engineering purposes.

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).

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.

Book Description
This book contains eight chapters treating the stability of all major areas of the flexural theory. It covers the stability of structures under mechanical and thermal loads and all areas of structural, loading and material types. The structural element may be assumed to be made of a homogeneous/isotropic material, or of a functionally graded material. Structures may experience the bifurcation phenomenon, or they may follow the postbuckling path. This volume explains all these aspects in detail. The book is self-contained and the necessary mathematical concepts and numerical methods are presented in such a way that the reader may easily follow the topics based on these basic tools. It is intended for people working or interested in areas of structural stability under mechanical and/or thermal loads. Some basic knowledge in classical mechanics and theory of elasticity is required.
