東京大学大学院 工学研究科
有理BスプラインやB-Repモデルによって表現された形状モデルと、オブジェクト指向型のデータ構造により表現した有限要素モデルとを統合化したモデルを提案し、それに基づいたFEMモデリングシステムを構築することによって、船体等の３次元の実構造物における解析モデルの生成・修正が容易になることを示した。さらに、システム構築にオブジェクト指向データベースを導入することにより、データの管理が容易になることを示した。

<p> Stiffeners are essential members of ship hull structures composed of stiffened panels, and their scantling formulae against lateral pressure are important for designing safe and rational hull structures. In typical scantling formulae of classification societies, the reduction in the fully plastic moment due to the shear stress is not directly considered in the current design.</p><p> In this study, we first derived a simple formulation of the shear stress effect with the simultaneous action of an axial stress under a given stiffener configuration and showed that the reduction of the fully plastic moment can be calculated using three non-dimensional parameters. Based on the formulation, we discussed how each parameter contributes to the fully plastic moment as well as the condition under which the shear stress can be effectively neglected. Subsequently, we used finite element analysis (FEA) based on the residual deflection criterion, thereby verifying the validity of the theoretical proposals. Finally, we proposed a scantling formula, rationally taking account of the shear stress effect.</p>
