摘要

This paper presents an experiment and an analysis for examining the response and failure of round-hole 6061-T6 aluminum alloy tubes with different hole diameters and hole directions subjected to cyclic bending. The moment-curvature response demonstrated an almost stable and closed hysteresis loop from the first bending cycle. The hole diameters and directions had almost no influence on the loop configuration. However, the ovalization-curvature behavior depicted an asymmetrical, ratcheting, and bow trend with the increase in the number of bending cycles, while hole diameters and directions exhibited a strong influence on this relationship. Finally, the finite-element software ANSYS was employed to describe the moment-curvature and ovalization- curvature relationships, and an empirical model was proposed to simulate the relationship between the controlled curvature and the number of bending cycles required to ignite failure. As a result, the experimental and analytical data were found to agree well.
