DOI: 10.1007/s00158-018-2090-4
Abstract: In this work, we propose to extend the bi-directional evolutionary structural optimization (BESO) method for compliance minimization design subject to both constraints on volume fraction and maximum von Mises stress. To this end, the aggregated… read more here.
