FUNCTIONALLY GRADED MATERIAL DESIGN FOR PLANE STRESS STRUCTURES USING PHASE FIELD METHOD

We present a functionally graded material design (FGMD) approach relying on a topology optimization procedure based on asymptotic homogenization and phase-field method. We also introduce a complete framework from which numerical results lead to 3D printed structures. We firstly present numerical experiments to verify the proposed methodology and, subsequently, we discuss experimental measurements comparing optimized FGMD with a constant density structure having the same weight. Experimental evidence shows the effectiveness of the proposed methodology in improving the overall stiffness of optimized structures.
