摘要：

This paper addresses the experimental and numerical analysis of a novel design of adhesive joint. So the consistency of the data could be verified, a statistical study was performed that considered not only the sample size population but also the statistical differences between the single-lap and wavy-lap joints. In addition to experimental tests, a finite element analysis was carried out to analyze the stress fields inside the joints. The results show an average increase of nearly 41% on loading. This fact could be due to the compressive stress field developed inside the wavy-lap joint. Moreover, this stress field distribution can also be the reason for the adherent delamination observed in the wavy-lap joints. So far, the modified wavy-lap joint seems to lead to stronger joints.
