Fracture mechanics and fatigue in offshore structures.

Journal Article

Considers the basic principles of fracture mechanics, covering the definition of stress intensity factor and stress concentration factor. Tabulates representative formulas for these factors. Examines the modes of crack opening and the concept of plane strain fracture toughness. Fatigue life determination by S-N curves fails to take account of crack growth. Discusses crack growth models, the problem of existing flows, fatigue crack growth rate prediction and factors affecting the rate of crack growth. Examines deterministic and probabilistic analyses with consideration of fatigue analysis, cumulative damage and dynamic effects. Examples are given. (C.J.U.)
