Abstract
In this study, we developed a modeling technique that simplifies the C6L bolt-jointed A6N01S-T5 aluminum alloys by using shell elements and beam elements. We set the equivalent pressure area around the bolted joints, and the nodes in the area were connected to the beam element as rigid region by using constraint equations. We measured the stress of the bolted joints specimen from strain gauges under the quasi-static loading test, and calculated those by FE analysis. The analytical stress and shear load agreed well with the experimental results. By using this modeling method of bolted joints, we can evaluate the distribution of shear load of each bolt with a large quantities of bolted joints.
