薄板のスティフナ形態の最大剛性設計法 : 第1報,連続構造モデルによる取り扱い

An optimum design technique of the stiffner layout which gives minimum compliance is developed. A thin plate with stiffners is treated as an anisotropic plate of pseude-continuous structure, and is discretized into the finite elements. The minimum compliance design subjected to the constant volume, it which the distributions, of angles of the stiffner arrangement and the stiffner densities are varied, is determined by the recursive quadratic programming technique. By applying this design technique, the optimum layout of the stiffner of the rectangular plate under some typical loading and supporting conditions are obtained.
