Topology optimization of compliant mechanisms with multiphase anisotropic materials

The study aims at providing a method for topology optimization of compliant mechanisms with multiphase anisotropic materials. The element stacking method is adapted to establish multiphase anisotropic materials interpolation model. The mutual strain energy of the mechanism is maximized under the volume constraint. The numerical example demonstrates the availability of the design method. The comparison of the results with single-phase anisotropic materials shows that the mutual strain energy of the compliant mechanism with multiphase anisotropic materials is greater.
