Abstract: In this study, an experimental tests and numerical analysis is carried out on hybrid/ weld-bonded single-lap joints, in comparison with the spot welded and adhesively bonded joints. A low carbon steel D513 and EDD materials are used. Experimental tests have been carried out for spot weld, adhesive bonded and weld bonded specimens to find the tensile –shear strength of the joints. Epoxy adhesive Terokal 4555B is used to fnd out the maximum load bearing capacity of adhesive bonded and weld bonded joints. Same models are modeled in hyper mesh and analysed with the Ls-Dyna software to validate the experimental results. Using this finite element model, the stress distributions were simulated in terms of Von mises stress in the overlap region. The force–displacement curves of the test results are compared with those of the simulation results.. The effect of changing overlap length showed different strength advantages, upto 26% compared to the spot welded joints and 4% over the adhesive bonded joint.
