In this paper, by considering the 3D geometry, the ISSF variation along the butt-joint interface side is discussed to explain the experimental results. The results show that the critical ISSF distributions when debonding occur are almost the same and independent of the adhesive bondline thickness. The validity of the 2D modelling is investigated experimentally for two kinds of brittle and ductile adhesives considering the location of the maximum ISSF. It is found that the adhesive strength can be expressed as a constant value of the ISSF at the center side and also at the corner of the adhesive interface.}, title = {Variation of intensity of singular stress field (ISSF) along the interface outer edge of prismatic butt joint and debonding condition expressed by the ISSF}, volume = {102}, year = {2020}, yomi = {ノダ, ナオアキ and サノ, ヨシカズ and タカセ, ヤスシ} }
