摘要:
概述了目前的几种管道弯曲屈曲临界应变预测评估方法，重点介绍了弯管横截面椭圆化的理论解决方案，并分析了它们各自的适用性。为了确定目前最合理有效的预测评估方法，对几种管道弯曲屈曲临界应变公式的预测结果与试验数据以及有限元计算结果进行了对比分析。分析结果表明，针对管道弯曲屈曲临界应变的预测，在大多数情况下，屈曲塑性变形引起的截面椭圆模型给出的预测结果比其他屈曲应变预测方法的结果更切实际。
Abstract:
In this article, it introduced current several assessment methods for assessing pipeline plastic bending buckling strain, emphasized the theory solution of bending pipe cross-section ovalization, and analyzed the applicability. In order to determine the most reasonable and effective prediction assessment method, the comparison among prediction of pipe bending critical buckling strain formula, test data and finite element calculation results was conducted. The analysis results indicated that the section elliptical model prediction result caused by buckling deformation is more reasonable than that of other buckling strain prediction in most cases.
