ABSTRACT

The aim of this contribution is to study, how the homogeneized coefficients qij depend on the shape of w and how this information can be used in material optimization of composite structures. Since we shall use the optimal shape design approach, we shall consider the restricted c lass 0 of admissible inclusions w, defined as follows :

o = {w I w is a simply connected domain contained in Y, satisfying the ,),-cone property, meas w = 8 } ,

where ,), and 8 are given positive numbers.
