Design of cellular materials for multiscale topology optimization: application to patient-specific orthopedic devices

Abstract A flexible problem-specific multiscale topology optimization is introduced to associate different areas of the design domain with diverse microstructures extracted from a dictionary optimized unit cells. The generation carried out by exploiting micro-SIMP AnisoTropic mesh adaptivitY (microSIMPATY) algorithm, which promotes free-form layouts. proposed methodology particularized in proof-of-concept setting for orthotic devices treatment foot diseases. Different patient-specific settings drive prototyping customized insoles, are numerically verified and successively validated terms mechanical performances manufacturability.
