Mechanistic Aspects of Fracture I—Brittle Fracture Models
Erschienen in: Fundamentals of Hydrogen Embrittlement
Brittle fracture models proposed as the mechanism of hydrogen embrittlement are presented. Notions based on the Griffith theory on crack instability and its criteria are explained. Hydrogen effects are included in the parameters used in the criteria. However, the involvement of plasticity is crucial even for brittle-like cases, and various expressions for the effects of plasticity in the crack instability criteria are described.
