- Abstract
METHODS FOR PIPE defect assessment are described, particularly for gouges, dents, and combined gouge and dent defects. Due to the fact that these defects induce elastoplastic failure, the assessment methods are based on limit analysis or notch fracture mechanics, and both provide close safety factors. In this paper the following methods are described: for gouges - limit analysis and notch fracture mechanics; for dents - a ductility criterion; for combined gouges and dents - a method based on notch fracture mechanics taking into account stress triaxiality.
