This paper presents topology optimization based on a semi-analytical method (SBFEM) problems involving materials using (MIST). The does not have volumetric issues presence incompressibility and it pass inf-sup stability conditions without requiring any mesh-dependent stabilization parameters. Thus is also possible SBFEM. solutions stress strain are derived semi-analytically. response function MIST chosen as mutual energy density which formulated by obtained Numerical examples including optimal design compressible well rubber mounts containing solid fluid presented. present results verified available reference results.
