Paper Abstract

In this study, the stress distributions in single lap joints subjected to static load were measured by photoelasticity, and the effects of Young's modulus ratio of dissimilar adherends and the adherend thickness on joint strength were examined. In addition, the strains were measured when a joint was subjected to an impact load. It is seen that singular stresses occur at the edges of the interfaces. It is also seen that the joint strength increases as Young's modulus of the adherends and the adherend thickness increase. FEM analyses are carried out when joints are subjected to impact loads. The measured results are compared with the numerical results. Discussions are made on the behavior of single-lap adhesive joints.
