接着継手の予想強度と実験値の比較

抄録

This paper is concerned with a comparison of predicted strength based on the proposed way explained in the 1st report, and experimental results of adhesive joint strength. It is shown that the strength of scarf joints can be predicted by the strength law represented by stress, that of double lap joints can be predicted by strain, and that of single lap joints can be predicted by the energy release rate. The experiments on the effect of scarf angle on the strength of scarf joints, and on the effects of lap length, adherend thickness and adhesive thickness on the strength of double lap joints and single lap joints are performed. As a result, it is shown that the experimental strength agrees well with the predicted strength.
