Abstract
The aim of present paper is to investigate the dynamic strength characteristics of LNG cargo containment system under sloshing impact loads numerically. The dynamic stress transmission mechanism under the impact load was analyzed based on the dynamic Finite Element Analysis. Based on the insights obtained from the numerical studies, the characteristics of internal stress distribution and stress concentration have been reported. The material option including anisotropic material features required for the commercial FEA code application were suggested based on the comparison with the experimental results.
