Evaluation of Fracture Toughness for Power Plant Materials Using Continuous Indentation Technique

Article Preview

Abstract:

An indentation fracture toughness model is applied to estimate non-destructively the fracture toughness of power plant materials such as ASTM A53 and ASME SA335 P91. Fracture toughness evaluated using the model showed good agreement with current standard fracture toughness test results.
