引張せん断荷重を受ける単純重ね合わせ接着継手の弾塑性有限要素解析 An Elasto Plastic Finite Element Analysis of Single-Lap Adhesive Joints Subjected to Tensile Shear Loads.
Stress distributions in single-lap adhesive joints are analyzed using an elasto plastic finite-element method in order to predict joint strength. With an increase of tensile shear load, adherends tend to be yielded and the interface then starts to peel. The peel process and the yielded regions of the adherends are examined with an increase of the tensile shear load. The effects of rigidity and yield stress of adherends and so on are clarified on the peel process. It is seen that the peel stress increases with a decrease of adherend rigidity. In addition, the joint strength is estimated taking the peel produced at the inter face, by the von Mises's criterion. Experiments concerning joint strength were performed. The numerical results are in fairly good agreement with the experimental ones concerning joint strength. It is shown that joint strength increases as the adherend rigidity increases.
