“…To obtain more general ISSF for evaluating interface strength, several analytical techniques were applied [21][22][23][24][25][26][27][28]. One of the most used numerical modelling techniques is the finite element method, which can be used for many engineering applications conveniently [29][30][31][32][33][34][35]. In order to obtain the ISSF, a mesh-independent technique was proposed for two-dimensional butt joints.…”

“…is very accurate since they are the same independent of the mesh size. Therefore, for example, by focusing on the middle point of the side, the ISSF ratio can be expressed as the FEM stress ratio as shown in equation (1) [15,16,20].…”

“…FEM can be used for many engineering applications conveniently [17][18][19].They found that the ISSF at the interface corner of two-dimensional butt joint decreases with decreasing the adhesive thickness. Also, Noda et al [20] obtained the critical ISSF for Suzuki's experimental specimen by using two-dimensional butt joint models, and found that the adhesive strength c  can be evaluated as a constant critical ISSF ( for carbon steel/epoxy resin. In this paper, by considering real specimen 3D geometry, the ISSFs on the interface outer edges of 3D butt joints will be analysed by varying the adhesive thicknesses to confirm the validity of previous 2D modelling.…”

Abstract. Adhesive joints are extensively used in various manufacturing processes in different industrial sectors because of its high fatigue resistance. Different materials properties cause the singular stress field, whose intensity is depending on the adhesive joint geometry. Our previous studies show that debonding strength can be expressed as a constant value of the critical intensity of singular stress field (ISSF) by using two-dimensional butt joint models. By considering real specimen geometry, in this paper, the ISSFs on the interface outer edges of three-dimensional butt joints are analysed by varying the adhesive thicknesses. A meshindependent technique combined with three-dimensional finite element method (FEM) is shown to evaluate the ISSF. The ISSF distributions on the interface outer edges are analysed in comparison with the previous two-dimensional results. It is found that the critical ISSF considered 3D geometry is almost constant independent of the adhesive thickness.

Hearth rolls are the most important tools in continuous annealing line to produce thin steel sheet. Usually, the roll surface is coated by ceramics using thermal spraying. However, material mismatch and temperature change may cause thermal stress leading to the failure of the coating and deteriorating high adhesive strength and wears resistance. Therefore, it is very important to improve the debonding strength by optimizing the design of spray coating. The traditional method of evaluating the debonding strength of spray coating is prescribed as JIS H8304 thermal test. This paper focuses on the intensity of singular stress field (ISSF) at the end of interface since few research is available in terms of ISSF. Previously, the authors considered the JIS specimen assuming a plane strain. However, since the hearth roll is cylindrical and axi‐symmetric, the difference between plane strain and axi‐symmetric models should be clarified. Thus, in this paper, the axi‐symmetric model is newly considered and the optimum design is discussed by varying the coating material and the coating thickness. Also the present results are compared with the previous results of JIS specimen so that the difference between actual model and JIS specimen can be clarified to contribute the design and evaluation of the real rolls.
