`failure. An overview of different nondestructive inspection techniques
`is presented in section 1.6.2
`
`1.6.2 NonWe Inspection (NDI)
`
`Non-Destrudive Inspection (NDI) can be defined as the use of
`non-intrusive methods to determine the integrity of a material or
`structure. Many non-intrusive methods have been developed to
`evaluate materials for property determination to verify quality of
`workmanship. and to screen a component for the existence of flaws. A
`flaw.
`in this sense. can be considered as any nonconfonnity that
`exceeds anestablished size criteria.
`Improper NDI
`inspection
`methods for flaw detection, or lack of interval inspections on fracture
`critical hardware can lead to premature failure of structure and loss of
`life.
`
`in
`important aspect of NDI
`Flaw detection is by far the most
`regards to safe-life assessment of fracture critical parts. Fracture
`mechanics analysis assumes the existence of a maximum flaw size in
`the part that grows in a stable manner during its service life. NDI
`provides the assurance that a flaw larger than the identified maximum
`size does not exist in the part. From a safety parapective. the initial
`assumed crack lengths provided by the NDI methods are larger than
`any pro-existing flaw that could be present
`in the structure after
`inspection. However. the degree of conservatism as a result of the
`larger initial crack size assumption (used to evaluate the life) must be
`realistic enough not
`to impact
`the structural weight or cause
`unnecessary rejection of parts.
`
`There are numerous NDI methods utilized for flaw detection in
`
`structural components [40]. Although many specialized methods are
`developed for specific materials and configuration, most techniques
`are variations on a
`few general methods which use visual
`enhancement of defects or measure some form of energy transmission
`through materials and its interaction with defects. The most prevalent
`of the NDI techniques commonly used in the detection of flaws in
`aerospace and aircraft components are:
`liquid penetrant, magnetic
`particle. eddy current. ultrasonic. and radiography. The purpose of this
`section is to briefly describe the different NDI methods, to explain in
`simple
`language the
`physical phenomenon of non-destrudtve
`inspection, it's application, and to discuss the variables affecting them.
