Concurrent optimization of structural topology and infill properties with a CBF-based level set method

Long JIANG, Yang GUO, Shikui CHEN, Peng WEI, Na LEI, Xianfeng David GU

Frontiers of Mechanical Engineering 2019, Volume 14, Issue 2,   Pages 171-189 doi: 10.1007/s11465-019-0530-5

Abstract: The proposed CBF parameterization ensures an explicit impose of the lower and upper bounds of the designof the conventional RBF-based parametric level set method, where the lower and upper bounds of the designboundary layer using the shape-preserving conformal mapping method, which leads to a hierarchical physical structureis expected to provide a timely solution to the increasing demand for multiscale and multifunctional structuredesign.
