【 摘 要 】

Presently, lot of emphasis is given on joining of dissimilar materials. Around 60-70% of the structures are failing at the joints. Therefore, it is critical to investigate the failure load and failure mode of dissimilar materials joint. The present work investigates the failure of single lap single bolted joints mainly on shear and bending strength. Two material combination joints such as Mild Steel - Aluminum and Mild Steel - Glass fiber reinforced polyesters bolted joints are analyzed using experimental and finite element methods. Present investigation shows that the Mild Steel - Glass fiber reinforced polyesters has better shear strength and bending strength than the Mild Steel - Aluminum material joint.
