The Behavior of Sandwich Structures of Isotropic and Composite Materials

by JackR. Vinson

Overview

The Behavior of Sandwich Structures of Isotropic and Composite Materials presents the mathematics, descriptions, and analytical techniques in the growing field of sandwich structures. From a background in sandwich structures to thermoelastic problems of sandwich structures and sandwich shell theory, the book provides the knowledge needed to analyze, design, and optimize various sandwich structures.

As one would expect from a book on sandwich structures, this volume discusses special failure modes such as face wrinkling and core shear instability. Coverage includes not only honeycomb cores, but also foam, web, and truss cores. An important topic in composite structure design, optimization is explored in two chapters on sandwich plates and sandwich shells. The author presents the optimization techniques in closed form and the methods are applicable to material selection and geometric design. The book also contains a set of problems and references at the end of each chapter. This text is ideal for engineers-in-training, as well as practical engineers who desire a comprehensive understanding of sandwich structures technology.

Editorial Reviews

"Most composite textbooks focus on basic laminate theory. This is an important subject, but it will only get you so far. At some point, you will need to move beyond simple point stress analysis and start looking at complex structures.
One of Jack Vinson's earlier books, The Behavior of Structures Composed of Composite Materials, has long been on my list of essential references. It starts with a brief review of lamination theory, then gets right into the analysis of beams, plates, and shells. It is a graduate level textbook, but could be targeted to advanced seniors.
The Behavior of Sandwich Structures picks up where The Behavior of Structures leaves off. It essentially covers the same types of structures, but at a more advanced level. It also covers some new subject areas like structural optimization.
Any sandwich structure, whether it has isotropic or anisitropic facesheets, can be treated as a composite. Traditional composite theories can be used, with the important addition of transverse shear effects.
Governing differential equations are given for beams, plates, and shells. Several solution methods are outlined, including both direct solutions and energy methods. Solutions for some specific geometries and boundary conditions are worked out in full, but most are left as an excercise (this is a textbook, after all). Governing equations and solutions cover static and dynamic loads, thermal and moisture effects, and eigenvalues (natural frequencies and stability).
As one would expect from a book on sandwich structures, special failure modes such as face wrinkling and core shear instability are discussed. Core materials aren't limited to honeycomb, but also include foam-cores, web-cores, and truss-cores.
One of the more important topics in composite structure design is optimization, and Dr. Vinson provides two chapters on the subject: one for sandwich plates; and one for sandwich shells. The optimization techniques are all closed form, so you
