Homogenization-based topology optimization integrated with elastically isotropic lattices for additive manufacturing of ultralight and ultrastiff structures

The integration of topology optimization with lattice structures has shown great potential for the additive manufacturing (AM) lightweight superior mechanical properties and multifunctional characteristics. To further improve design manufacturability, structural efficiency, isotropy computational homogenization-based (HMTO) method was proposed to integrate plate–lattices exhibiting excellent elastic isotropy. validity demonstrated by comparing optimized models conventional composed truss–lattices solid materials. Results show that highly improves stiffness energy absorption capability.
