Suitability of mixed-mode I/II assessment methods for implementation into the SINTAP procedure

Several engineering methods are available for the assessment of structures containing defects. They belong essentially to two categories: FAD methods and CDF methods. The recent SINTAP procedure unifies both FAD and CDF routes for the assessment of mode I loaded defects. In this paper, fracture assessment methods containing guidelines for mixed-mode I/II loading conditions are examined and compared with the aim to discuss their suitability for implementation into the SINTAP procedure.
