Abstract:

The project concerned the development of a novel design methodology for structural mechanics. The developed design methodology was inspired by the EvoDevo processes in biological evolution. Thus the methodology uses a cellular division process or branch growth model to define the development of the topology of the structure. With the topology in place, a physico-mathematical model is used to determine the fitness of the design generated by the developmental process. Then an evolutionary algorithm evolves the set of rules defining the development of the structure topology, and therefore the topology itself. The methodology developed, called bioTOM, has been assessed in a number of test cases, ranging from classic benchmark problems, to realistic design problems. From the solutions obtained in these studies, it can be concluded that bioTOM provides a significant improvement, both in efficiency and design performance, when compared with existing methodologies, including gradient based methods or evolutionary algorithms for topology optimization of structure topology.
