Internal rotary inspection system (IRIS) is an ultrasonic method for the nondestructive testing of pipes and tubes. The IRIS probe is inserted into a tube that is flooded with water, and the probe is pulled out slowly as the data is displayed and recorded. The ultrasonic beam allows detection of metal loss from the inside and outside of the ...

The technique is very sensitive and can detect tight cracks. Surface inspection can be performed both on ferromagnetic and non-ferromagnetic materials. [8] [9] Tubing inspection is generally limited to non-ferromagnetic tubing and is known as conventional eddy current testing.
The equation and chart needed to apply Newmark's method is based entirely on the principles of the theory of elasticity.There are however limitations to these theories that one must realize when they are applied to an actual soil.
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
James C. Newman is an American engineer and materials scientist known for his work on fracture and fatigue for aerospace vehicles. NASA has listed him as a "Superstar of Modern Aeronautics". [ 1 ]
Step 1: The UT probe is placed on the root of the blades to be inspected with the help of a special borescope tool (video probe). Step 2: Instrument settings are input. Step 3: The probe is scanned over the blade root. In this case, an indication (peak in the data) through the red line (or gate) indicates a good blade; an indication to the left ...
Computer-aided inspection (CAI) is the use of software tools to assess manufactured objects. [ 1 ] [ 2 ] It is closely related to computer-aided design (CAD) and computer-aided manufacturing (CAM). Its primary purpose is to allow engineers to more quickly and precisely assess the physical properties of manufactured objects.
