Bearing Capacity Finite Element Model and Solution of High-Pressure Gas Nonmetal Glass Steel Pipeline

High-pressure nonmetal has good corrosion resistance, but also has significantly different steel based performance parameters. Based on the Von Mises yield criterion material nonlinearity, ideal elastic-plastic stress-strain relations and bilinear servo aggrandizement criterion, nonmetal pipeline load-bearing finite element analysis model has been established by using Shell 99 unit, COMBIN14 spring unit, Solid46 unit. In order to choose a big deformation analysis model, revised Newton- Raphson method is used to solve the incremental balance equation in an iteration way. The experimental measurement error for 41MPa rupture pressure compared is 3.21%, which indicates that the established finite element model and the solving method are correct and reasonable.
