Abstract:

A material property gathering format is proposed with the objective that the database so developed be suitable for deriving statistical measures mean values, standard deviations, types of distributions of the property required by reliability and design Engineers. Emphasis is placed on strength and toughness properties of marine steels and their welds. The format developed and reported in the SSC report 352 was modified by incorporating the findings from a review of the material property representation formats reported in literature and an assessment of statistical data processing requirements. Finally, the concept of hierarchy of the data fields is proposed to facilitate estimation of statistical measures in cases where insufficient data for a specific property is available. The hierarchy approach enlarges the database by ignoring the lowest ranked fields which perceived to have the least influence on the property under consideration. Recommendations are made regarding the next steps that ought to be undertaken to have available a working databasesoftware package
