鋼のスカーフおよびバット継手の引張接着強度 Ｉ ぜい性接着剤の場合 Adhesive Tensile Strength of Scarf and Butt Joints of Steel Plates : 1st Report, A Case of Brittle Adhesive
Adhesive tensile strength of scarf joints with various scarf angles and butt joints with various adhesive layer thicknesses have been measured to study fracture criterion of joints of steel plates bonded by brittle epoxy adhesive. For those joints, three-dimensional elastic stress analysis was performed by FEM. Fracture of both joints were explained quantitatively by introducing the boundary layer depth of 0.035 mm at free surfaces of adhesive layers and obeyed maximum principal depth of 0.035 mm included most of stress concentrated area at free surfaces. Locations of fracture initiation and fracture modes of adhesive layers observed with a optical microscope and a scanning electron microscope were agreed with those expected from stress distributions and boundary layer conception.
