Beschreibung
Zusammenfassung:	A stress mapping system and method is operable to determine and map stresses along a conduit. The system includes a tool movable along a conduit and having at least one sensing device for sensing characteristics of the conduit, and a processor operable to process an output of the at least one sensing device. Responsive to processing of the output by the processor, the processor is operable to determine stresses at a surface of the conduit. Responsive to the processing of the output of the at least one sensing device, and responsive to a determination of a location or position of the tool along the conduit, the system generates a map of determined stresses along the conduit. The map of determined stresses provides a visual representation of the stresses determined at and along the surface of the conduit.
