| Abstract: | Blowout preventers are important devices on oil wellhead.A 3-D model of blowout preventer case and mechanics analysis is established.Carrying capacity is accomplished by use of MSC Nastran Software and the elastic-plastic character of material is considered.In limit carrying capacity and multi-loading,stress distribution and the load into plastic status and plastic zone is analyzed,thus to offer the basic of proved design safety,reasonable and further design. |
| Keywords: | blowout preventer nonlinear analysis finite element stress |
