Multiscale Topology Optimization
Designs obtained by multiscale topology optimization method
Multiscale topology optimization (MTO) is the simultaneous optimization of macroscale topology and microscale structure. MTO holds the promise of enhancing product-performance beyond what is possible today. With the advent of additive manufacturing, the resulting multiscale structures can be fabricated with relative ease but high computational cost and loss of microstructural connectivity pose a challenge. In this project, we are trying to tackle these challenges.
