Cohesive failure verification and fracture origin identification when the adhesive strength is expressed as a constant ISSF
Source abstract
Abstract
The aim of this paper is to explain that the ISSF evaluation method can apply when the fracture is cohesive as well as an interface fracture. The cohesive fracture usually occurs very close to the adhesive joint`s interface controlled by the intensity of singular stress field (ISSF). This is the reason why the adhesive strength can be evaluated as a constant value of ISSF. In this study, the fracture origin is confirmed at the interface end to verify the ISSF evaluation method. Next, the cohesive fracture near the interface is confirmed since the slight amount of adhesive remains near the polished streaks of the adherend steel. Finally, it is found that the cohesive fracture very close to the interface guarantees the appropriate adhesive strength which can be expressed as a constant value of the ISSF.
