Abstract:

© 2016, Editorial Office of Chinese Journal of Computational Mechanics. All right reserved. This study presents a method for finding optimum topology of cellular structure made from one material using an appropriate addition manufacturing process and tailored with different volume fractions in different structural domains. The topology optimization problem is firstly formulated allowing multi-volume fractions in cellular structures. An algorithm based on MIS T with multi-thresholds is presented and interfaced with commercial finite element analysis software. Numerical examples for the minimum mean compliance problem with three volume fractions are presented to illustrate the present algorithm. The present numerical results show that, for the optimum topology design with three volume fractions, there exists an optimum combination that yields an additional 10% reduction in the minimum mean compliance when compared to the design with two volume fractions.
