Abstract

The objective of this paper is to investigate the dynamic strength characteristics of LNG carriers cargo containment system under impact loads experimentally. The material properties were experimentally obtained for individual components of MARK III insulation system. A series of impact tests was performed using a custom-built drop experiment facility as varying heights and weights of the drop object. Crack initiation and propagation were measured during the cyclic dry drop experiment. The quantitative relationship between impact load and crack initiation as well as the cycle number and crack propagation were reported.
