Abstract
Stress characteristics in adhesive scarf joints of dissimilar adherends subjected to impact loads are analyzed in an elastic region using three-dimensional FEM. An impact load is applied to a joint by dropping a weight. The end of the upper adherend is fixed and the other end of the lower adherend is subjected to an impact load. The effects of scarf angles and combination types of the adherends, the adhesive thickness and Young's modulus of the adhesive on the stress behavior at the interfaces are examined. In addition, experiments were carried out to measure the strain response of the adhesive scarf joints subjected to impact tensile loads using strain gauges. A agreement is seen between the tendencies of the analytical and experimental results.
