Fig. 27. Effect of the gap bolt-hole on the load transferred by the bolt vs. the external tensile load .

5. Conclusions

s to obtain a reduction of the shear stress , as regards induced ver, it was observed that the load transferred by the to the peel by preload is

From numerical analyses it was observed that the use of the bolt allow acting on the adhesive layer in comparison of the simply adhesive bonded joint. However stress, there is not a reduction of the peak stress values because of the compression action limited in the range of the contact zone of the bolt head. Moreo bolt increases when:

• the strength of the structural adhesive reduces • the preload acting on the bolt reduces; • the gap between bolt’s shank and hole reduces. ;

Finally, at the same load condition, the double bolt configuration allows the mechanical elements than the single bolt configuration.

to obtain a greater load transfer through
