Buckling Analysis of Tapered Composite Plates Using Ritz Method Based on Classical and Higher Order Theories


Book Description

Tapered composite plates are being used in various engineering applications such as helicopter yoke, robot arms and turbine blade in which the structure needs to be stiff at one location and flexible at another location. In the present thesis, the buckling of different types of tapered composite plates are analyzed based on classical laminated plate theory, first-order shear deformation theory and third-order shear deformation theory. The developed formulation is applied to the analysis of various types of tapered composite plates. The efficiency and accuracy of the developed formulation are established in comparison with available solutions, where applicable. A detailed parametric study has been conducted on various types of tapered composite plates, all made of NCT/301 graphite-epoxy, in order to investigate the effects of boundary conditions, laminate configuration, taper angle and the thickness ratio.

ICCS19 19th International Conference on Composite Structures


Book Description

Nowadays, it is quite easy to see various applications of fibrous composites, functionally graded materials, laminated composite, nano-structured reinforcement, morphing composites, in many engineering fields, such as aerospace, mechanical, naval and civil engineering. The increase in the use of composite structures in different engineering practices justify the present international meeting where researches from every part of the globe can share and discuss the recent advancements regarding the use of standard structural components within advanced applications such as buckling, vibrations, repair, reinforcements, concrete, composite laminated materials and more recent metamaterials. For this reason, the establishment of this 19th edition of International Conference on Composite Structures has appeared appropriate to continue what has been begun during the previous editions. ICCS wants to be an occasion for many researchers from each part of the globe to meet and discuss about the recent advancements regarding the use of composite structures, sandwich panels, nanotechnology, bio-composites, delamination and fracture, experimental methods, manufacturing and other countless topics that have filled many sessions during this conference. As a proof of this event, which has taken place in Porto (Portugal), selected plenary and keynote lectures have been collected in the present book.

The Mechanics of Smart Nanocomposite Sandwich Structures


Book Description

This book explores the mechanics of smart nanocomposite sandwich plates, discussing various relevant theories of mechanical analysis such as buckling, vibration and dynamic instability. It presents different models for obtaining the effective material properties of nanocomposite structures such as Mori-Tanaka, mixture, micro-electro-mechanical and Halpin-Tsai. In addition, the basic equations for smart materials are introduced, while the governing equations for various examples are derived on the basis of the energy method and Hamilton’s principle.










Buckling of Structures


Book Description

This collection of papers, written by friends and colleagues of Josef Singer, presents a comprehensive and timely review of the theoretical mechanics of thin shell-structures. Topics of great current interest such as the buckling of composite plates and shells, the plastic buckling of thin-walled structures and the optimum design of buckling sensitive curved composite panels are examined by experts, using a great diversity of approaches, whereby theoretical predictions are compared with experimental results whenever possible.Other topics reviewed include the buckling and post-buckling behaviour of imperfect shells under different external static or dynamic loads and a variety of boundary conditions. Papers dealing with the vibration and the dynamic response of thin elastic bodies are also presented.A strong emphasis is made on the practical applications aspect in the theories presented. Thus engineers, research workers and students who are involved with the design and analysis of shell structures made of different materials, and subjected to various static and dynamic loads will find this volume an invaluable source of reference.
