Fatigue requirement development for hull structures

Authors: Ye.V. Baskakova, S.V. Petinov

Abstract

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.
