The problem of finding the shape of an elastic inhomogeneity that minimizes stress concentration is investigated. A class of ellipsoidal inhomogeneities is identified that serve as minimizers for inclusions which are softer than the matrix. For hard inclusions, strain minimizing ellipsoidal inhomogeneities are described. In both cases, rather simple isoperimetric inequalities are derived.
