Book Description
An experimental study of the prebuckling, incipient buckling, and postbuckling behavior of thin-wall aluminum cylindrical shells with a nominal R/h of 100 and subjected to pure bending is reported. The investigation includes initially-undamaged and cutout-predamaged cylindrical shells. The types of predamage include: (a) a single circular hole (three different diameters were employed) and (b) a single slotted hole of fixed size and aspect ratio but oriented axially (phi = 0 degrees), obliquely (phi = 45 degrees), or circumferentially (phi = 90 degrees). Emphasis is given to studying the load-deflection behavior and the associated buckling patterns in the postbuckling range, for both monotonically-increasing angular deflections of the buckled region and unloading-reloading behavior. Load-deflection characteristics and buckling patterns distinctive to each type of specimen tested are presented for bending rotations extending to about 15-20 degrees. (Author).

Book Description
The object of this book is to clarify the whole aspect of the basic problems concerning the elastic stability of of circular cylindrical shells under typical loading conditions. The book deals with buckling, postbuckling and initial postbuckling problems under one of the three fundamental loads, that is, torsion, pressure and compression. The emphases are placed on the accurate analysis and comprehensive numeral results for the buckling problem, experimental verification of the theoretical analysis for the postbuckling problem and clarification of the range of applicability of the perturbation method for the analysis of initial postbuckling behaviors and imperfection sensitivity. The problems under typical combined loads as well as the influence of the contained liquid are also clarified.

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.

Book Description
A theory developed by W.T. Koiter for the initial postbuckling behavior of thin-walled shells is applied in an analysis of the imperfection sensitivity of ring-and-stringer stiffened cylinders subjected to axial compression. The cylinders are considered to be simply supported, and both eccentricity and torsional rigidity of stiffeners are taken into account. Values of a so-called imperfection sensitivity parameter are determined for particular stiffened cylinders, and the suitability of the parameter as a practical measure of imperfection sensitivity is examined. Theoretical results are correlated with available data for the experimental buckling loads of stringer stiffened cylinders. The evidence for the suitability of the parameter as a practical measure of imperfection sensitivity is judged to be promising but not conclusive. (Author).

Book Description
Buckling and initial postbuckling of an oval cylindrical shell under pure bending and under combined uniform axial compression and bending is investigated. The first and second order stability equations are developed from the Donnell-type equations which are shown to be appropriate. The solution of these two sets of equations determines, respectively, the buckling characteristics and a 'sensitivity parameter'. The buckling loads are found to be in good agreement with the engineering approximation based upon the assumption that buckling occurs when the local axial stress equals that corresponding to the classical buckling stress of a locally equivalent circular cylindrical shell under uniform axial compression.

Book Description
ENTAL STUDY OF THE PRE-BUCKLING AND POSTBUCKLING BEHAVIOR OF THIN ALUMINUM CYLINDRICAL SHELLS WITH R/h of 100 under a pure applied torque is reported. The investigation includes initially-undamaged and pre-damaged cylindrical shells. The types of predamage include a single circular 1-inch diameter hole, and a single size rectangular slot (3/8-inch wide and 2.10-inch long) with orientations of 0, 45, and 90 degrees to the longitudinal axis of the cylindrical shell. Postbuckling behavior of these specimens is investigated for large twist angles, for both monotonically-increasing angular deflections and for unloading-reloading behavior. Load-deflection characteristics and buckling patterns distinctive to each type of specimen tested are presented. Finally, comments are offered on idealizing these buckling patterns for possible use in the future development of approximate methods for predicting these types of postbuckling load-deflection behavior.
