Identification of cohesive zone model parameters based on interface layer displacement field of bonded joints

Abstract: Nowadays, adhesively bonded structures are widely used as structural elements in many engineering fields. The development of approaches for predicting joint reliability and interface layer behavior make adhesives suitable for new and more complex applications. In this paper, a novel identification methodology of cohesive zone model (CZM) parameters, based on the comparison of experimental and numerical relative adherends slip displacements, is proposed and compared with approaches by literature. All considered… Show more

“…According to previous studies, 48,49,55–57 many factors could affect the solutions of reverse analysis, for example, maximum tangential stress, fracture energy, viscosity coefficient, and initial tangential stiffness. In order to study the effects of CZM parameters and CZM shape on the load versus displacement curves, those factors are investigated.…”

“…Tauheed and Datla 11 proposed a framework for determining the parameters of the mode‐I TSL of an adhesive joint using a direct method by studying mode‐I fracture of DCB specimens made with carbon fiber‐reinforced polymer (CFRP). Cricrì et al 12 used the experimental and numerical relative adherend slip displacements as the comparison parameter to determine the CZM parameters and compared them with other approaches in the literature.…”

“…CZMs are incorporated into the numerical techniques using the cohesive elements characterized by cohesive or traction–separation laws (TSL). Particularly, CZMs are of special interest for many researchers in adhesive bonded joints because of their ability to anticipate the failure behavior of both brittle and toughened adhesives, as well as thick and thin adhesive layers 36–39 …”

“…Particularly, CZMs are of special interest for many researchers in adhesive bonded joints because of their ability to anticipate the failure behavior of both brittle and toughened adhesives, as well as thick and thin adhesive layers. [36][37][38][39] Belytschko et al 40 analyzed the dynamic fracture in concrete using the CZMs through the EFG framework and proposed that the EFG method is reliable for this task. Klein et al 41 used reproducing kernel particle method (RKPM) and compared several cohesive approaches of that time (bulk and surface cohesive formulations).…”
