Multi-Physics Inverse Homogenization for the Design of Innovative Cellular Materials: Application to Thermo-Elastic Problems

Blog Article

We present a new algorithm to design lightweight cellular materials with required properties in a multi-physics context.In particular, we focus on a thermo-elastic setting by promoting the design of unit cells characterized both by an isotropic and an anisotropic behavior with respect to mechanical and thermal requirements.The proposed procedure generalizes the Course a pied - Femme - Vetements - Manteau microSIMPATY algorithm to a thermo-elastic framework by preserving all the good properties of the reference design methodology.The resulting layouts exhibit non-standard topologies and are characterized by very sharp contours, thus limiting the post-processing before manufacturing.

The new cellular materials are compared with the state-of-art in engineering practice in terms of thermo-elastic properties, thus highlighting the good performance of the new layouts which, in some yellow cable cases, outperform the consolidated choices.
