Layout of tileable multistable structures using topology optimization

Abstract

This work presents a formulation for the design of tileable bistable structures using a topology optimization method. Modeling is based on a ground structure approach, where each member is represented using a non-linear beam. A member is either hinged or fixed at either end and a rubber-like material is used to model the hinges. The optimization is implemented using a genetic algorithm. The methodology developed is illustrated with an example. © 2006 Springer.
