摘要:
采用弹塑性有限元法,结合非线性屈曲理论,分析了受初始几何缺陷影响的管线钢管在内压作用下的非线性屈曲。在分析中考虑了内压和管体缺陷等因素的影响。结果表明,考虑几何缺陷的有限元模型能够较好地模拟实物试验的屈曲载荷和屈曲形态。
Abstract:
The elastic-plastic finite element method was combined with non-linear buckling theory to analyze the buckling behavior of line pipe with geometrical imperfection under internal pressure.Internal pressure and pipe body defects were considered in the analysis.The results showed that the critical load and the modality of buckling behavior can be simulated by the finite element model.
