Abstract
Extremal materials may exhibit mechanism like behaviours. Examples are negative Poisson’s ratio materials that expand transversely when pulled horizontally. Such materials are often composed of periodic arrays of simple microscopic mechanisms and may therefore be called Periodic Micro Mechanisms (PMMs). This chapter describes how PMMs can be systematically synthesized using the topology optimization method. A number of examples including design of negative Poisson’s ratio, negative thermal expansion coefficient and band gap PMMs are given.
