Fatigue requirement development for hull structures
Authors: Ye.V. Baskakova, S.V. Petinov 

Basic provisions for and trends of developing the modern rules of structural design for fatigue as well as resource appraisal for ships in service. The distinctive features of design S-N curves and correction methods for stress concentrations in structural nodes for formats "Nominal stress - Hot spot stress - Notch stress" are analyzed. The need for the data base elaboration in respect of S-N curve calculation are analyzed and suggestions for its development are given. 

Key words: hull structure fatigue, design fatigue curves, stress concentration, damage summation, remaining life.
