Paper Title:
Nonlinear Stability Analysis on Vessels Subjected to External Pressure
  Abstract

To determine stability performance and the critical load of the short cylinder vessel which is made of steel, this paper carried out the finite element linear buckling analysis for 5 meters long steel pressure vessel and obtained buckling critical load. Then performed the nonlinear instability analysis by the arc-length method and obtained the load-displacement curves of the overall stability of the pressure vessel structure. The critical load can be got by twice the elastic slope method and double-tangent intersection method, and the loads are slightly higher than the result of the theoretical calculation, so the result of the theoretical calculation is safe and reliable. Finally, several measures keeping stability of short cylinder pressure vessel are proposed.
