FRACTURE MECHANICS AND FATIGUE IN OFFSHORE STRUCTURES.
The contemporary macroscopic view of fatigue damage as crack growth from inadvertently introduced flaws to critical-length cracks provides a powerful analytical methodology for the structural engineer. This chapter outlines the fundamentals of this relatively young engineering science with a view toward applying it to designing against fatigue and fracture in modern offshore structures. Subjects covered include crack opening mode, fracture toughness, fatigue life, crack growth models, preexisting flaws, fatigue crack growth rate, calculation examples, deterministic and probabilistic analyses, sensitivity of fatigue damage calculations, recommended practice, and others.
