The idea from which the method originated came from the growth behavior of living things, such as trees or bones, responding to a stress accompanying a load. On the use of the method, the optimum shape is formed by iterating a usual elastic analysis and incremental growth analysis by using a constitutive equation of growth with the result of the elastic analysis, without a particular technique for mathematical optimization programming or a steep extension of memory for calculation of the sensitivity. The growth law is given as a relation between incremental growth strain and a deviation of objective stress indicating the strength from basic stress. Two examples of a cantilever beam loaded at its tip and a column loaded at its tip under the influence of gravity are analyzed to show the effectiveness of the proposed method.日本機械学会1988-12jpnjournal articlehttp://hdl.handle.net/2237/7260https://nagoya.repo.nii.ac.jp/records/56540387-5008日本機械学会論文集 A編5450821672175https://nagoya.repo.nii.ac.jp/record/5654/files/JSME-A54-2167.pdfapplication/pdf979.3 kB2018-02-19
