中文摘要 | 本文以內涵時間理論結合虛功原理、有限元素分析軟體ANSYS和有限元素分析軟體ABAQUS來描述圓管承受循環彎曲負載時的彎矩-曲率及橢圓化-曲率關係。在本研究中,兩種不同尺寸的316L不銹鋼圓管承受循環彎曲負載下的行為也進行實驗的測試。當與實驗結果比較後發現,三種方法皆可良好的描述彎矩-曲率的關係。然而,內涵時間理論結合虛功原理比有限元素分析軟體ANSYS和有限元素分析軟體ABAQUS所描述的橢圓化-曲率關係較接近實驗結果。 |
英文摘要 | In this paper, the endochronic theory combined with the principle of virtual work and finite element analysis softwares, ANSYS and ABAQUS, are used for simulating the moment-curvature and ovalization-curvature relationships of circular tubes subjected cyclic bending. Two different sizes of the 316L stainless steel circular tubes subjected to cyclic bending are tested in this study. When compared with experimental data, it is shown that three methods lead to good simulation of the moment-curvature relationship. However, the endochronic theory combined with the principle of virtual work has the closer simulation of the ovalization-curvature response with the experimental data than the simulations by finite element analysis softwares, ANSYS and ABAQUS. |
