引張せん断荷重を受ける二重重ね合わせ接着継手の弾塑性有限要素解析と強度について Elastoplastic Finite-Element Analysis of Double-Lap Adhesive Joints Subjected to Tensile Shear Loads.
Stress distributions in double lap adhesive joints are analyzed using an elastoplastic finite-element method in order to predict the joint strength. The effects of the yield stress and Young's modulus of the adherends and the lap length on the stress distributions in the joints are demonstrated. In addition, the joint strength is estimated taking into account the peel fracture produced at the interface, by von Mises's criterion. Experiments were also performed. The analytical results are in fairly good agreement with the experimental results concerning the joint strength. It is seen that the joint strength increases as the adherend rigidity increases. In addition, it is shown that the joint strength of double-lap joint is twice as large as that of a single-lap joint when the yield stress of the adherends is increased.
