摘要
以玻璃纤维增强柔性管为研究对象,通过理论及有限元方法对其在内压拉伸组合荷载下的力学性能进行研究,最终得到其在组合和荷载的极限方程,该极限方程的计算结果与有限元算例结果高度吻合,证明了极限方程的可靠性,同时,该极限方程也为管道设计人员提供了可靠、简便、准确的内压拉伸组合荷载下极限状态校核。
Taking glass fibre reinforced thermoplastic composite pipe as the research object,its mechanical properties under internal pressure tensile combined load is studied by theory and finite element method,and finally its limit equation under combination and load is obtained.The calculation results of the limit equation is highly consistent with the results of finite element examples,which proves the reliability of the limit equation,The limit equation also provides a reliable,simple and accurate limit state check under combined internal pressure and tension load for pipeline designers.
