Necessary Conditions and Minimal Extensionsvariational problems that makes the problem stable against these variations. The extended Lagrangian gives an upper bound for the quasiconvex envelope. We follow (Cherkaev, 1999). The method is based on the classical variational technique that requires a comparison of nearby configurations, rather t

Multimaterial Compositesosites. The topology of optimal microstructures is more diverse and less systematized. In the first section we demonstrate the variety of optimal multicomponent structures, and in the second section we develop a systematic approach to these problems based on necessary conditions.

Elasticity of Inhomogeneous Mediaroperties of the equations of elasticity needed for optimization of elastic structures. For detailed discussion of the theory of linear elasticity we refer to the textbooks (Timoshenko, 1970; Lurie, 1970a; Gurtin, 1972; Sokolnikoff, 1983; Atkin and Fox, 1990; Lurie, 1990a; Parton and Perlin, 1984a;

These possibilities have stimulated an interest in the mathematical foundations of structural optimization. The challenge of this book is to bridge a gap between a rigorous mathematical approach to variational p

Domains of Extremal Conductivityproaches, which are driven by different arguments but lead to similar results. Each approach has an analogue for the one-dimensional variational problem discussed in Chapter 1, and each approach will be developed for more general multidimensional problems.

Supplement: Variational Principles for Dissipative Mediaticity, etc. Time-periodic fields in such media are described by linear differential equations for complex-valued potentials. The properties of the media are characterized by complex-valued tensors, for example, by complex permeability or complex elasticity tensors.
