Topology optimization has been shown efficient in the design of microstructures to target extreme elastic or thermos-elastic properties, as pioneered with the SIMP method. In this study, we investigate the influence of graded interfaces on the effective properties and final design. To this end we adopt a level-set based shape and topology optimization framework which incorporates recent developments to account for graded and non monotonic variations of materials properties across the interface between two neighboring bulks. We focus on the problem of extreme thermoelastic properties. Results available in the literature with sharp interfaces are revisited and the governing mechanisms to reach zero or negative c.t.e. are highlighted. We then evaluated how multi-materials and graded interfaces can push forward know thermoelastic bounds. The methodology and selected results will be presented.
