Abstract

In this paper, the mechanical behavior and buckling failure of 6061-T6 aluminum alloy tubes with different chop depths subjected to cyclic bending were experimentally investigated. It can be seen that the moment-curvature relationship exhibits a steady loop from the first bending cycle. And, the chop depth has almost no influence on the moment-curvature relationship. However, the ovalization-curvature relationship exhibits an increasing and ratcheting manner with the number of the bending cycles. In addition, higher chop depth of a tube leads to a more severe unsymmetrical trend of the ovalization-curvature relationship. Furthermore, the 6061-T6 aluminum alloy tubes with five different chop depths were tested, five unparallel straight lines were found for the controlled curvature-number of cycles to produce buckling relationship in the log-log scale. Finally, the theoretical model proposed by Kyriakides and Shaw in 1987 was modified in this study for simulating the controlled curvature-number of cycles to produce buckling relationship. Through comparison with the experimental data, the theoretical model can properly simulate the experimental findings.
