failure study of hybrid bonded-bolted composite single and double lap joints

In this paper by employing ansys workbench software and threedimensional finite element simulation, failure analysis of hybrid bonded and bolted single and double lap joints with laminated composite adherends subjected to axial, shear and bending loads were performed. in order to select an appropriate and optimized element number, the convergence behavior of single and double lap joints were investigated. then the failure study of each single and double lap hybrid composite joints for the three time dependent loading cases were performed. to demonstrate the validity and precision of the presented simulations, the obtained results were compared with the results presented in the available literatures. the results of this research indicated that, in the single lap joint subjected to axial load, the replacement of hybrid bonded bolted joint instead of adhesive joint leads to significant increase of 56% in the load bearing capacity of the joint.
