Mechanics of Classical Sandwich Structures

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.
