In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...

The interference-fit size has a significant effect on the riveted lap joints of CFRP/Al alloy laminates. requirements for are different because strengthening heterogeneous materials. However, in riveting process alloys, laminates lead to poor structural strength requirements. Therefore, differently assembled molds designed acquire novel size, and tensile test is adopted evaluate their propertie...

Friction stir lap welding of 7B04 aluminum alloy was conducted in the present paper, and the effect of welding speed on the defect features and mechanical performance of lap joints was investigated. The results indicate that the hook defect at the advancing side (AS) can reduce the effective thickness of the top sheet, and the sheet thinning level is gradually lowered by increasing the welding ...

A three-dimensional finite element modeling is developed using ABAQUS software. This includes riveted and rivet-bonded joints models. Both models undergo thermal heat caused by hot-driven rivet process and then are subjected to a constant velocity at one of its strip edges to simulate the shear tensile test up to the failure point. The developed FE models were based on elastic-plastic propertie...
