“…As the cyclic process continues, the ovalization keeps accumulating. A similar test result was also reported by Kyriakides and Shaw (2) for 606l-T6 aluminum and l018 steel tubes and Hsu et al (9) for titanium alloy tubes. Figure 8 shows a picture of the local buckling of the 316L stainless steel tubes under cyclic bending.…”

“…The tubes used by them were the same as that used by Pan et al (1) Pan and Her (8) investigated the response and stability of SUS 304 stainless steel tubes subjected to cyclic bending with different curvature-rates. Hsu et al (9) investigated the elastoplastic response and stability of titanium alloy tubes subjected cyclic bending and Lee and Pan (10) investigated the viscoplastic response and stability of titanium alloy tubes subjected cyclic bending. Lee et al (11) discussed the influence of the diameter-tothickness ratio to the response and stability of SUS 304 stainless steel tubes subjected to symmetrical cyclic bending.…”

This paper presents the experimental and theoretical results of the response and collapse of 316L stainless steel tubes subjected to cyclic bending. The tube bending machine and curvature-ovalization measurement apparatus(1) were used for conducting the curvaturecontrolled experiment. It was found that the response and collapse are similar to that of metal tubes found in literatures. Next, the endochronic theory and the principle of virtual work were used to simulate the response of 316L stainless steel tubes under cyclic bending. In addition, a proposed theoretical formulation (2) was used to simulate the relationship between the controlled curvature and the number of cycles to produce buckling. It has been shown that the theoretical simulations of the response and collapse correlate well with the experimental data.

“…Experiments and theoretical studies have been carried out on smooth tubes of various materials, such as 304 stainless steel, 310 stainless steel, 316L stainless steel, and titanium alloy pipes (ASTM B338 Grade 2). The following behaviors were studied: tubes under cyclic bending (Hsu et al 24 ; Chang and Pan 25 ), tubes under cyclic bending with different curvature rates (Pan and Her 26 ; Lee and Pan 27 ; Chang et al 28 ), tubes with different D o /t ratios under cyclic bending (Lee et al 29 ; Lee et al 30 ; Chang et al 31 ), tubes under cyclic bending with different mean curvatures (Pan and Lee 32 ), tubes under cyclic bending with different mean moments (Chang et al 33 ), and tubes under pure bending creep (Lee and Pan 34 ).…”

This paper presents an experiment and analysis to investigate the response and failure of 6061-T6 aluminum alloy round-hole tubes with different hole diameters of 2, 4, 6, 8, and 10 mm subjected to cyclic bending at different curvature ratios of −1.0, −0.5, 0.0, and +0.5. The curvature ratio is defined as the minimum curvature divides by the maximum curvature. Four different curvature ratios are employed to highlight the mean curvature effect. It can be seen from the experimental results that the moment-curvature relationships gradually relax and become steady states after a few bending cycles for curvature ratios of −0.5, 0.0, and +0.5. The ovalization-curvature relationship depicts an asymmetrical, ratchetting and increasing as the number of bending cycles increases for all curvature ratios. In addition, for each hole diameter, the relationships between the curvature range and the number of bending cycles necessary to initiate failure on double logarithmic coordinates display four almost-parallel straight lines for four different curvature ratios. Finally, this paper introduces an empirical formula to simulate the above relationships. By comparing with experimental results, the analysis can reasonably describe the experimental results.
