シェル要素とビーム要素を用いた長穴ボルト締結部モデル化手法の検討

抄録

In order to accurately predict the stress distribution on aluminum-alloy plates with a slotted hole for each through which the plates are fastened by a steel bolt, we applied a spider model which is the Finite Element Method composed of shell and beam elements. As a result, the analysis of the model can be accurately predicted trend of stresses without showing abnormally high stress near fastening section.
