“…Here, 𝜎𝜎 𝑧𝑧0,𝐹𝐹𝐹𝐹𝐹𝐹 𝑃𝑃 and 𝜎𝜎 � 𝑧𝑧0,𝐹𝐹𝐹𝐹𝐹𝐹 𝑃𝑃 are the singular and non-singular stress at the interface end in the butt joint model obtained by axisymmetric FEM analysis, respectively, 𝜎𝜎 𝑦𝑦0,𝐹𝐹𝐹𝐹𝐹𝐹 𝑃𝑃𝑃𝑃𝑃𝑃 is the singular stress at the interface end in the bonded plate model obtained by 2D FEM analysis. Since 𝐾𝐾 𝜎𝜎 𝑃𝑃𝑃𝑃𝑃𝑃 has been analyzed by Noda et al accurately [12], 𝐾𝐾 𝜎𝜎 𝑃𝑃 can be obtained by Eq. (3).…”

In this study, the fatigue fracture criterion of the adhesively bonded joint is discussed. The singular stress field is formed at the interface end in the butt joint and causes the debonding fracture. The singular stress field is represented with the intensity of singular stress field (ISSF). The static debonding strength of the adhesively bonded joints is expressed with a constant value of critical ISSF. The rotating-bending fatigue tests are carried out on the butt joints of 15mm in diameter with four different adhesive thicknesses of 109 - 159μm, 209 - 265μm, 393 - 432μm and 754 - 841μm. The evaluation method by the ISSF is applied to the experimental results. It is found that the fatigue strength of the butt joint can be expressed with the constant value of critical ISSF.
