	<span lang=\"EN-US\">In this paper, the mechanical behavior and
buckling failure of SUS304 stainless steel tubes with different local
sharp-notched depths subjected to cyclic bending were experimentally
investigated. It can be seen that the experimental moment-curvature
relationship exhibits cyclic hardening and becomes a steady loop after a few
cycles. However, the experimental ovalization-curvature relationship exhibits
an increasing and ratcheting manner with the number of the bending cycles. In
addition, higher notch depth of a tube leads to a more severe unsymmetrical trend
of the ovalization-curvature relationship. It has been observed that the
notch depth has almost no influence on the moment-curvature relationship. But,
it has a strong influence on the ovalization-curvature relationship. Finally,
the theoretical model proposed by Kyriakides and Shaw [1] was used 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</span>
