The aim in this paper is to minimize the time integration of squared displacement error norm on the responded mode and the prescribed mode by varying a boundary shape under a volume constraint. The shape sensitivity is derived using the Lagrange multiplier method and the formula of the material derivative. A procedure to solve this problem using the traction method is presented,which one of the authors has proposed as an approach to solving domain optimization problems.The validity of proposed method is verified by applying to basic numerical examples.journal article日本機械学会2001-04application/pdf日本機械学会論文集65667611617http://hdl.handle.net/2237/723503875008https://nagoya.repo.nii.ac.jp/record/5629/files/JSME-A67-611.pdfjpn日本機械学会
