Investigation of the Failure Load in Riveted Lap Joints Made of Aluminum Alloys
摘要
Riveted lap joints are common in complex structures, and failure of these joints can lead to failure of the entire structure. In the riveted lap joints, single-row rivets may critically fail in the rivet or edge because of less contact area, support, and edge distance. The failure behavior of riveted aluminum alloy lap joints under tensile load is investigated to prevent this. The experiment is performed on 2024-T3 aluminum alloy specimens fabricated from 2 mm thick sheets and NAS1097AD6-7 solid rivets made of 2117-T4 aluminum alloy. The metallic lap joints are arranged in a single row with one, two, and four rivets. The primary objective is to investigate the failure load of a single-row riveted metallic lap joint and the behavior of the plate and rivet under shear load. A stress–strain plot is obtained from the experiment, and the rivet and edge failure behavior is investigated. Also, from FE model of riveted lap joint is simulated based on Jonson-Cook damage model.
