... corrosion erosion structural engineering thickness measurement The key principle used in developing this tool employs the basic geometric properties of a thin annulus. With respect to an axis, the moment of inertia of an area is defined as the sum of the products obtained by multiplying each...

... for this effect, which is sometimes referred to as signal wrap around, to ring down. This limits the maximum pulse repetition rate to about 50 pulses per second. This is adequate for average wall thickness measurements but not for flaw inspection. We would like to thank Gas Technology Institute and Pipeline...

... vibrations thickness measurement stress-strain relations Pressure vessels were first used in the form of gun barrels but are now encountered in diverse applications such as high pressure water jet cutting 1 . Until 1830, boilers worked at a pressure of about 7 psi. The use of better materials...
