The paper reports the study carried out for the realization of a composite-to-metal tubular joint of a steel flange adhesively bonded to a carbon fiber epoxy composite shaft subjected to traction and torsion. In particular a finite element method has been employed to study the yielding of the adhesive and to characterize the stress concentration associated with the boundary effect at the ends region of the adhesive layer. For this analysis, essential data are the actual mechanical properties of the adhesive, such as Young’s modulus, Poisson’s ratio and yield shear deformation, that are independent of the joint geometry, adherends properties and load. In this work a critical analysis of the factors that influence strength and other stress measurements is reported and a method to obtain useful data using single-lap specimen is described.

Abstract
The paper reports the study carried out for the realization of a composite-to-metal tubular joint of a steel flange adhesively bonded to a carbon fiber epoxy composite shaft subjected to traction and torsion. In particular a finite element method has been employed to study the yielding of the adhesive and to characterize the stress concentration associated with the boundary effect at the ends region of the adhesive layer. For this analysis, essential data are the actual mechanical properties of the adhesive, such as Young’s modulus, Poisson’s ratio and yield shear deformation, that are independent of the joint geometry, adherends properties and load. In this work a critical analysis of the factors that influence strength and other stress measurements is reported and a method to obtain useful data using single-lap specimen is described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
