Topological derivatives for contact problems in ℝ3
Jan Sokołowski, Antoni Żochowski · 2011
Formulae for the first order expansions of the Steklov-Poincaré operators in the case of the Laplace operator and of the elasticity boundary value problems in singularly perturbed domains in ℝ3are presented. Such expansions are required for the evaluation of topological derivatives of the energy shape functionals.
