Multi-scale topolgy optimization
A phenominal performance to weight ratio
Although weight minimization for the multidisplanary problems are addressed in topology optimization, weight minimization is reaching the physical limit of the bulk material (i.e. the lighter the solid structures will be the more delicate). Nature is successfully dealing with this matter by implementing cellular structures (for example bones, and plants skeletons). To mimic the nature, the researcher started to making a porous design instead of bulk to furtherly decreasing the weight of the product, and with maintaining high strength and robustness at the same time. This led to implementing multiscale optimization to design macrostructure and microstructure at the same time. To perform integrated multiscale structural design, the macrostructures and the microstructures are designed simultaneously, to assimilate the spatial field response between microstructural properties (i.e. the effective elastic and heat conductivity tensors) and the macroscale layouts.
