title = "Fatigue assessment of a large container ship considering the effect of thickness and material",
abstract = "Along with rapid increase in the size of container ship for a few decades, it is required to use thicker plates in way of the hatch coaming than before. The use of higher tensile steel with yield strength 460 MPa is also inevitable to avoid using excessively thick plates. According to the recommendation of IIW and rule requirements of classification societies, it is defined that fatigue strength of welded joints is independent of the tensile strength and the effect of plate thickness is considered by mean of a correction exponent. Recently, to investigate the effect of plate thickness and tensile strength on fatigue strength for the weld joints, series of fatigue test were conducted on the specimens of butt weld joint and longitudinal fillet weld joint with the different plate thickness and tensile strength steel. From the test results of each series of specimens which were taking into account recent developments concerning material and welding techniques, the effect of plate thickness and material was investigated. In addition, considering the effect derived from this fatigue test, fatigue strength was calculated on butt weld joints and longitudinal fillet weld joints in way of hatch coaming top plate for a large container ship.",
