TY  - JOUR
AB  - This paper develops a robust framework forthe multiscale design of three-dimensional lattices with macroscopically tailored thermal and thermo-structural characteristics. A multiscale approach is implemented where the discrete evaluations of small-scale lattice unitcell  characteristics  are  converted  to  response  surfacemodels so that the properties exist as continuous functions of the lattice micro-parameters. The derived frame-work constitutes free material optimization in the space of  manufacturable  lattice  micro-architecture.  The  optimization  of  individual  lattice  member  dimensions  is enabled by the adjoint method and the explicit expressions of the response surface material property sensitivities. The approach is demonstrated by solving thermaland  thermo-structural  optimization  problems,  significantly  extending  previous  work  which  focused  on  linear structural response. The thermal optimization solu-tion shows a design with improved optimality compared to the SIMP methodology. The thermo-structural optimization solution demonstrates the method’s capability for attaining a prescribed displacement in response to temperature gradients.
