| Summary: | In present work, the bonded and spot weld-bonded of dissimilar materialsjoints for three dimensional models using the finite element technique werestudied for different adhesive thicknesses. The results show that the stressesin adhesive bonded joints are concentrated at the ends of the overlappedarea. When the spot-welding is combined with the adhesive bonding, thestresses are concentrated at the adhesive bond ends and at both ends of theweld nugget. The results show also that the stresses are more concentratedtowards the material of the lowest melting point. Changing the thickness ofthe adhesive layer for various dissimilar material models give us the optimalthickness for each case that one can use in designing lap joints of twodissimilar materials. The results in general show that the thinner the adhesiveis, the higher is the peak stresses developed in the weld-bonded joint. |
