Plate and Panel Structures of Isotropic, Composite and Piezoelectric Materials, Including Sandwich Construction


Book Description

Plates and panels are primary components in many structures including space vehicles, aircraft, automobiles, buildings, bridge decks, ships and submarines. The ability to design, analyse, optimise and select the proper materials for these structures is a necessity for structural designers, analysts and researchers. This text consists of four parts. The first deals with plates of isotropic (metallic and polymeric) materials. The second involves composite material plates, including anisotropy and laminate considerations. The third section treats sandwich constructions of various types, and the final section gives an introduction to plates involving piezoelectric materials, in which the "smart" or "intelligent" materials are used as actuators or sensors. In each section, the formulations encompass plate structures subjected to static loads, dynamic loads, buckling, thermal/moisture environments, and minimum weight structural optimisation. This is a textbook for a graduate course, an undergraduate senior course and a reference. Many homework problems are given in various chapters.




Mechanics of Classical Sandwich Structures


Book Description

This book treats the mechanical behavior of one-dimensional sandwich structures, a typicaloncept in the context of lightweight design. Such structures are composed of different constituent (e.g., layers) in order to achieve overall properties, which are better than for a single component alone. This book covers the basic mechanical load cases, i.e., tension/compression, bending, and shear. Based on this knowledge, different failure modes, i.e., plastic yielding, and global and local instabilities are investigated. In addition, an introduction to classic optimization problems, i.e., the formulation of an objective function (e.g., the weight of a structure) and corresponding restrictions, is included. The consideration here is limited to one- or two-dimensional design spaces, i.e., with a maximum of two design variables. For such simple cases, the minimum of the objective function can often be determined using analytical or graphical methods.




Stability and Vibrations of Thin-Walled Composite Structures


Book Description

Stability and Vibrations of Thin-Walled Composite Structures presents engineering and academic knowledge on the stability (buckling and post buckling) and vibrations of thin walled composite structures like columns, plates, and stringer stiffened plates and shells, which form the basic structures of the aeronautical and space sectors. Currently, this knowledge is dispersed in several books and manuscripts, covering all aspects of composite materials. The book enables both engineers and academics to locate valuable, up-to-date knowledge on buckling and vibrations, be it analytical or experimental, and use it for calculations or comparisons. The book is also useful as a textbook for advanced-level graduate courses. - Presents a unified, systematic, detailed and comprehensive overview of the topic - Contains contributions from leading experts in the field - Includes a dedicated section on testing and experimental results




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.







Perovskite and Piezoelectric Materials


Book Description

Investigating in the area of perovskite materials and the fabrication of devices for properties in optoelectronics, we have presented a brief outline of perovskite materials. The authors present a fairly comprehensive arrangement of this very active area of research, with its past changes and present position and outlooks. Discussions are presented regarding photocatalysis, fabrication of solar cell devices and their stability, lead-free materials, as well as thermoelectric and piezoelectric applications. In view of the present status of perovskite materials, I am assured that each chapter of the book will be of boundless encouragement for researchers, scientists, and academicians working in this field.

FRP Composite Structures


Book Description

The use of fiber-reinforced polymer (FRP) composites in infrastructure systems has grown considerably in recent years because of the durability of composite materials. New constituent materials, manufacturing techniques, design approaches, and construction methods are being developed and introduced in practice by the FRP composites community to cost-effectively build FRP structural systems. FRP Composite Structures: Theory, Fundamentals, and Design brings clarity to the analysis and design of these FRP composite structural systems to advance the field implementation of structural systems with enhanced durability and reduced maintenance costs. It develops simplified mathematical models representing the behavior of beams and plates under static loads, after introducing generalized Hooke’s Law for materials with anisotropic, orthotropic, transversely isotropic, and isotropic properties. Subsequently, the simplified models coupled with design methods including FRP composite material degradation factors are introduced by solving a wide range of practical design problems. This book: Explores practical and novel infrastructure designs and implementations Uses contemporary codes recently approved Includes FRP case studies from around the world Ensures readers fully understand the basic mechanics of composite materials before involving large-scale number crunching Details several advanced topics including aging of FRPs, typical failures of structures including joints, and design simplifications without loss of accuracy and emphasis on failure modes Features end of chapter problems and solved examples throughout. This textbook is aimed at advanced undergraduate and graduate students and industry professionals focused on the analysis and design of FRP composite structural members. It features PowerPoint lecture slides and a solutions manual for adopting professors.




Optimization Methods in Structural Design


Book Description

This book offers an introduction to numerical optimization methods in structural design. Employing a readily accessible and compact format, the book presents an overview of optimization methods, and equips readers to properly set up optimization problems and interpret the results. A ‘how-to-do-it’ approach is followed throughout, with less emphasis at this stage on mathematical derivations. The book features spreadsheet programs provided in Microsoft Excel, which allow readers to experience optimization ‘hands-on.’ Examples covered include truss structures, columns, beams, reinforced shell structures, stiffened panels and composite laminates. For the last three, a review of relevant analysis methods is included. Exercises, with solutions where appropriate, are also included with each chapter. The book offers a valuable resource for engineering students at the upper undergraduate and postgraduate level, as well as others in the industry and elsewhere who are new to these highly practical techniques.While the specific application is to structural design, the principles involved can be applied far more widely.
