Popis: Mark Ⅲ CCS plate is considered in this paper to perform its strength assessment. Mark Ⅲ CCS plate is designed and constructed by stacking various non-metallic engineering materials such as plywood, triplex and reinforced PU foam that are supported by series of mastic upon inner steel hull structure. From the viewpoint of structural analysis, this plated structure is treated as a laminated anisotropic structure. Commercially available general purpose finite element analysis programs such as MSC PATRAN and MARC are used to develop the finite element (FE) model of the Mark Ⅲ CCS plate. Because of the characteristics of LNG cargo that the Mark Ⅲ CCS plate deals with, it is subjected to a wide range of temperature variations, i.e. about -163℃ to 20℃. Different material properties of the Mark Ⅲ CCS plate at these temperature levels are considered in the FE model. Using the developed FE model, strength assessment procedure is developed incorporating various anisotropic failure criteria such as Hashin, Hill, Hoffman, Maximum stress and Tsai-Wu. The strength assessment is performed within the initial failure state of the Mark Ⅲ CCS plate and, as a result, failure details such as failure locations and loads are identified.
