Fracture mechanics and fatigue in offshore structures.

Journal Article

The fundamentals of the theory of fatigue damage, as crack growth from flows to critical length cracks, are examined. Representative formulas for stress concentration factors in various joints used in offshore structures are tabulated. Modes of crack opening, fracture toughness, and fatigue life are defined. Crack growth models are discussed in detail, followed by equations and theory for deterministic and probalistic analyses. Spectral analysis techniques are emphasized and the sensitivity of fatigue damage calculations and recommended practice are briefly considered. (A.J.)
