Topology optimization of a continuum with bimodulus material under multiple load cases (MLC) is investigated by using material replacement method. Using traditional methods to solve such a problem will encounter two difficulties for the sake of the stress-dependent behavior of bimodulus material. One is the nonlinear behavior of bimodulus material. The other is the definition of local material property under MLC. The present method can overcome the difficulties easily. It contains three major...[Show more]
