    • Abstract
  • The authors investigated systematically the BSI PD6493 advanced assessment method and EPRI engineering method based on ductile tearing.By the notion of maintainning equilibrium between driven and resistance forces under stable crack growth, established an optimization method for failure assessment.It possesses the characteristics of simplicity and clarification. Therefore, it eliminates the complexity and undeterminacy of various assessment diagram methods.The revised PD6493 advanced assessment method (1991) and EPRI engineering method possess similar precision probably, then their assessment results by ductile tearing may be trusted in the full senses.
