    摘要: Inspecting for fracture hazards by detecting a presence of at least one flaw development process in an equipment under inspection, the flaw development process being corrosion product nucleation and development, pitting, plastic deformation development, and/or micro-cracking. Detecting the presence of the flaw development process includes (a) determining at least one characteristic acoustic emission (AE) signature associated with a respective flaw development process, and (b) measuring an AE from each of a plurality of locations within the equipment. Presence of the respective flaw development process is identified only when the measured AE conforms to the characteristic AE signature within a predetermined tolerance. A fracture hazard is determined to exist only when (a) a quantity of the identified flaw development processes exceeds a first predetermined threshold and/or (b) a magnitude of at least one of the identified flaw development processes exceeds a second predetermined threshold.
