摘要: Abstract The derivation of a local criterion for cleavage fracture is presented in detail. In first part, brief review the metallurgical description step criterion. It shown that many cases critical stress OROWAN an adequate modelization. Statistical aspects test results are effect strain, temperature and strain rate discussed. second derived from WEIBULL's statistics used. Relationships between parameters this other usual using analytical solutions crack-tip situation. how can be implemented computer programs order to solve much more complex situations where no available. Some applications last approach discussed
