Mechanical Behavior and Failure of Riveting Joints in Tensile and Shear Tests

The main principle used by the designers of riveting joints is a shear condition of rivet material. In case of shear test of conventional riveting joints, their strength is determined by the mechanical properties of the fastener material. Hence, it is expedient to have more insight on the fracture mechanism of various joints during tensile tests. This paper discusses the strength of riveting joints of various sheet materials: DC01 steel, AW-5754 aluminum alloy, and their hybrid arrangements. We also analyze of the fracture mechanism of riveting joints in unilateral tensile tests of T-shaped specimens made of various sheet materials. The experimental results on the joint critical static load are compared with those obtained in the lap joint shear tests for the same rivet types.
