Details.
Determination of critical crack lengths using relevant standards and codes, fracture mechanics based finite element analysis, stress intensity factor and J-integral calculations, fracture toughness values derived from Charpy or similar testing, and environmental effects including stress corrosion cracking. Covers longitudinal and circumferential semi-elliptical surface cracks, elliptical embedded cracks, through cracks, single and multiple cracks, and opening, shearing and tearing fracture modes.
