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