Finite element analysis of adhesive joints in four-point bending load

Experimental and numerical analysis of single-lap joints for the automotive industry

“…The theory could not predict properly the joint strength because it did not include adherend yielding that occurred in the tests. Ozel et al [27,28] also studied the four-point bend test but used high-strength steel for the adherends. The effect of the adherend thickness, adherend overlap and type of adhesive was studied.…”

The effects of overlap length and adherend thickness on the strength of adhesively bonded joints subjected to bending moment

“…The schematic geometry of the specimen used in the experimental work carried out by Özel et al [11] and Kadioglu et al [12] is also shown in Fig 1. In these studies, hard steel adherends with three different thicknesses (1.6, 3 and 8 mm) were investigated and joints with only 25 mm overlap length were tested in the bending mode. More experimental details can be obtained in Refs [11,12].…”

“…In the analysis, the material nonlinearity based on the uniaxial stress-strain behaviors of adhesives (AV119 produced by Ciba Specialty Chemicals and Structural Bonding Tape (SBT) 9245 produced by 3M Company) and adherend determined from tensile tests was considered. More information on the mechanical behavior of the adhesives can be found in Refs [2,11]. In order to assess the effects of geometrical parameters on the performance of the joint for each adhesive under a bending load, four different adherend thicknesses and overlap lengths were investigated.…”

“…In order to avoid plastic deformation, as explained in Ref. [11], the adherend material was selected as hard steel. In the analysis, the material nonlinearity based on the uniaxial stress-strain behaviors of adhesives (AV119 produced by Ciba Specialty Chemicals and Structural Bonding Tape (SBT) 9245 produced by 3M Company) and adherend determined from tensile tests was considered.…”

“…For veri cation of the analysis, the FEA results were compared with experimental results, the details of which are given in Refs [11,12].…”
