Abstract: | The FE model of the circular TT joint in the offshore platform was set up in MSC/Patran.Non-linear analysis was carried out in MSC/Marc to study the ultimate strength of the TT-pipe joints under axial force,by NR method and Mises yielding criterion.The main factors affecting the ultimate strength of the TT-pipe joints were discussed,which laid a foundation for the reliability analysis of the TT-pipe joints. |
