Recent works in the boundary element method (BEM) community have been devoted to derivation of fast techniques perform matrix-vector product needed iterative solver. Fast BEMs are now very mature. However, it has shown that number iterations can significantly hinder overall efficiency BEMs. The robust preconditioners is inevitable increase size problems be considered. Analytical offer a interes...

In this paper we investigate the possibility of elastodynamic transformation cloaking in bodies made non-centrosymmetric gradient solids. The goal is to hide a hole from elastic disturbances sense that mechanical response homogeneous and isotropic body with covered by cloak would be identical corresponding outside cloak. It known case centrosymmetric solids balance angular momentum obstruction ...
