摘要:
应用有限元分析软件ANSYS ,对含点蚀缺陷的弯头在内压载荷作用下进行有限元分析,分析中考虑材料非线性和几何非线性,得出了缺陷尺寸对塑性极限载荷的影响及变化规律,得到了一些对含缺陷弯头的安全评定有参考价值的结论.
Abstract:
The pitting corrosion which is easy to form a hole on the gas pipe and bring to a lot of economic loss, is one of destructive local defect. In the paper, a computational method, FEM is adopted to calculate the collapse load of pressurized elbow with pitting corrosion, by taking the immense deformation effects and stress stiffening into consideration. The effect regulations of geometrical parameter on the plastic limit load were obtained and some referential conclusion to the secure assess of elbows with defect.
