Comparisons of Finite Element Models of Bonded Bonded Joints

Abstract:

Thispaperdealswithcomparisonsoffiniteelementmodelsofadhesivelybondedjoints. Inordertoincreasetheaccuracyoftheresults,fivelayersofsolidelementswereusedacrossthe adhesivelayerwhichwasonly0.05mminthickness.Thefiniteelementswererefinedgraduallyin steps from adherends to adhesive layer. In these models, most regions of the adherends and adhesiveweremodelledusingsolidbrickelementsbutsomesolidtriangularprismelementswere usedforasmoothtransition.Insomeofthemodels,linearinterpolationelementsoffullorreduced integrationandofhybridformulationwereused.Inothermodels,quadraticinterpolationelements of full or reduced integration and of hybrid formulation were used.
