The FEM Analysis of Membrane for LNG Storage Tank

LNG 저장탱크용 멤브레인 개발을 위한 유한요소해석

Analytical and experimental studies have been performed to investigate the strength of the membrane and the reaction force at the anchor point. Using nonlinear FEM code and experiments, the stress analysis of the corrugated membrane related the cryogenic liquid pressure and thermal loading is performed to ensure the stability and fatigue strength of the membrane. This paper reports on the FEM results of membrane.
