Multi-material robust topology optimization considering uncertainty of material properties

Multi-material robust topology optimization considering uncertainty of material properties

This paper proposes a solution to a multi-material robust topology optimization problem of density type considering material uncertainties based on H1 gradient method. A material interpolation with respect to the density is introduced using the rational approximation of material properties (RAMP) an...
