Topology optimization analysis by VOF method using triangular and tetrahedral elements 三角形・四面体要素を用いたVOF法によるトポロジー最適化法 三角形・四面体要素を用いたVOF法によるトポロジー最適化法 西宮, 裕騎 39276 阿部, 和久 39277 紅露, 一寛 39278 topology optimization VOF method CIVA method linear elasticity This paper presents a topology optimization method in which a structural layout is represented by the VOF function. The topological change results from the convection of the VOF function. The velocity field which leads the topology to an optimal design is derived by means of the sensitivity analysis. The proposed method is developed within the framework of the finite element analysis using triangular or tetrahedral elements. To prevent the numerical diffusion the CIVA method is employed in cooperation with the tangent transformation method. Applications to two- and three-dimensional minimum compliance problems are demonstrated. Through these numerical examples, the validity of the developed method is evidenced. journal article 土木学会 2006-08 application/pdf 応用力学論文集 9 353 363 応用力学論文集 AA12492021 13459139 https://niigata-u.repo.nii.ac.jp/record/2823/files/9_353-363.pdf http://hdl.handle.net/10191/24749 https://niigata-u.repo.nii.ac.jp/records/2823 jpn https://www.jstage.jst.go.jp/article/journalam1998/9/0/9_0_353/_pdf 公益社団法人土木学会 本文データは学協会の許諾に基づきJ-Stageから複製したものである
