Design of Composite Plates of Extremal Rigidity,d by different values of their elastic moduli; the amount of each material is given. We look for a distribution of the materials which renders the plate’s rigidity for either its maximal or minimal value. The rigidity is defined here as work produced by an extremal load on deflection of the points o

Calculus of Variations and Homogenization,with given measure γ’. Let .= α on ω and β on Ωω, and define . by . = 1 in Ω and . = 0 on the boundary. We want to find an ω which maximizes .. among all the measurable sets ω with given measure γ’..This optimal design problem has in general no solution. Indeed if there exists a smooth solution ω an

Microstructures of Composites of Extremal Rigidity and Exact Bounds on the Associated Energy Density,them composites of the minimal compliance or of the maximal stiffness). The composites are assembled from two isotropic materials taken in a prescribed proportion, and may be of an arbitrary microstructure..Two-sided bounds for the energy density are obtained for composites of maximal stiffness and

Book 1997oscopically heterogeneous mate rials. This activity brings together a number of related themes, including: ( 1) the use of weak convergence as a rigorous yet general language for the discussion of macroscopic behavior; (2) interest in new types of questions, particularly the "G-closure problem," mo
