Abstract
At present, the design of bone scaffolds cannot balance the combination of suitable porosity and proper mechanical property well, leading to difficulties in simultaneously facilitating bone tissue regeneration and avoiding the stress shielding phenomenon. In this chapter, a topology strategy of designing double-cone struts to reduce stress shielding of diamond-like porous metallic biomaterials while maintaining unvaried porosity is proposed. Porous metallic biomaterials developed from pentamode metamaterials (PMs) were rationally designed to mimic ...
