Morphologic Evolutionary Structural Optimization

This paper presents a new approach to evolutionary optimization of structural morphology based on two evolutionary paradigms. In the first one, the structural shape is optimized by simulating the growth process of natural structures. In the second one, the structural topology is optimized by removing material at low stress level. The proposed approach, called Morphologic Evolutionary Structural Optimization (MESO), combines these two design paradigms and leads to optimize simultaneously structural shape and structural topology. The extension of the proposed procedure to evolutionary optimization of non-homogeneous structures is also presented. The effectiveness of the procedure is shown through applications
