Topology Optimization for Chiral Elastic Bodies

摘要

The topology optimization problem is dealt with for linearly elastic chiral micropolar bodies. The maximum global stiffness is taken as objective function, and the material density as design variable. According to the SIMP model, the constitutive tensors are assumed to be smooth functions of the density. Optimal material distributions are obtained for several significant cases. Comparisons in terms of optimal configurations are made with classical Cauchy materials and centrosymmetric materials.
