Concurrent topology optimization design of material and structure within FE2 nonlinear multiscale analysis framework

This paper revisits concurrent design of material and structure within FE2 nonlinear multiscale analysis framework. For structural stiffness maximization at macroscopic scale, design variables are defined at the both scales. Cellular material models are defined at microscopic scale in a pointwise manner for the considered macroscopic structure. They are optimized to adapt the macroscopic structural physical response. Though linear models are...
