LNG 저장탱크용 멤브레인 성형공정에 관한 해석적ㆍ실험적 연구

Membrane structures are widely used for LNG(Liquefied Natural Gas) storage tanks. This study presents a membrane structure based on the Mark-Ⅲ type. For its development, a series of numerical simulation was conducted using ABAQUS and experimental investigation was carried out. The manufacturing process of the membrane was simulated. The thickness distribution predicted by the numerical approach agreed well with the experimental results.
