Dent Fatigue Life Assessment - Development of Tools for Assessing the Severity and Life of Dent Features

The objective of this research is to use elements of the previously validated dent assessment tool to develop a mechanical damage assessment strategy, validate it and ultimately develop an easily applied mechanical damage fatigue life assessment tool. The existing BMT dent assessment model will be further validated and used alongside the existing BMT plain dent geometry based severity ranking criteria to extend this criteria to: (1) consider dents interacting with welds; and (2) consider the effect of line pressure.
