摘要

•An FFT-based inverse homogenization approach is proposed for efficiently designing cellular materials.•Rotating architected materials with negative Poisson's ratio are generated.•Architected cellular materials with maximum stiffness and isotropy are sought out.•The inverse homogenization method for scaffold design with specified mechanical performance is validated.
