Optimization of Modular Truss Structures Composed of Wang Tiles

Popis výsledku v původním jazyce

The multi-scale problem of designing microstructures for a given macro domain is accompanied with high computational demands, scale separation issues, material discontinuities among cell boundaries, and non-manufacturability. The usual manner of approaching this problem is to employ a single periodic unit cell while sacrificing the optimality of the macro structure. On the contrary, the inverse homogenization-based optimization procedure performed independently at each point of the macro domain allows for arriving at discontinuous but almost optimal spatially varying microstructures. Both these methodologies rely inevitably on (local) microstructural periodicity. In this contribution, we introduce a modular-topology optimization method that exploits the merits of both the approaches, one of which allows for a design of connectable yet spatially varying microstructures of a bounded cardinality, their assembly plan within the macro domain, and which additionally supersedes the periodicity assumptions.
