Joint strength prediction of multiple blind rivet connections with macroscopic model
Bora Lee,Hanbyeol Namgung,손성국,Seongye Kang,김동철 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.2
Here, we present a macroscopic model of a blind rivet joint. To develop this model, the load-displacement curves of the blind rivet joint in the tensile and shear directions were measured by a single lap shear test, and a cross-tension test and optimization process were conducted. The model enables us to simulate various blind joint connections in components with high efficiency and accuracy and propose a specific joint strength per unit joint from the simulation results. Moreover, we analyzed the effect of the tensile strength and thickness of the plate on the joint strength per unit joint. As a result, we provide a prediction method for the number of joints for the component along with the proposed joint strength per unit joint for various materials and plate thicknesses.
