Synthesis of Bistable Periodic Structures Using Topology Optimization and a Genetic Algorithm. Prasad, J. & Diaz, a. R. Journal of Mechanical Design, 128(November):1298, 2006. ISBN: 1050-0472
doi  abstract   bibtex   
A formulation for the automatic synthesis of two-dimensional bistable, compliant periodic structures is presented, based on standard methods for topology optimization. The design space is parametrized using nonlinear beam elements and a ground structure approach. A performance criterion is suggested, based on characteristics of the load-deformation curve of the compliant structure. A genetic algorithm is used to find candidate solutions. A numerical implementation of this methodology is discussed and illustrated using simple examples.
