Topology optimization design of stretchable metamaterials with Bézier skeleton explicit density (BSED) representation algorithm
2020, Computer Methods in Applied Mechanics and EngineeringCitation Excerpt :For the design generated with BSED method, the designs are described by Bézier curve with certain thickness, the boundary can be smooth enough due to explicit geometric description without any limitation of FEM mesh resolution. The other merit of BSED is that it is easier to generate standard CAD model and edited in general CAD software [73], because the optimal design is described by parametric space, which is ready to directly define geometry in software using feature-based modeling [74], instead of converting the STL (stereolithography) file to ISO standard exchange format (i.e. STEP file [75]). Meanwhile, the number of design variables is reduced significantly compared to standard density-based method.
