UltraSpec™ has the capability to discriminate
between well-bonded signatures, partially bonded signatures, and debonded
signatures (including "kissing" debonds). Because UltraSpec™ uses a unique
spectrum analysis, resonance behavior in each layer of a bonded structure
is evaluated. |
|
Because of UltraSpec™’s ability to see a wide
range of frequencies in a single, continuous pulse, the attenuation as
a function of frequency can be monitored to measure the surface condition
(sensitivity can be user-defined). Additionally, the resonance behavior
of the material produces a very precise thickness measurement. Knowing
the thickness as well as the surface condition allows the user to quantify
corrosion even in its very early stages. |
|
UltraSpec™’s capability to define attenuation
as a function of frequency allows the user to establish signatures for
various material. Each new sample’s signal can be compared to these signatures
and evaluated for atypical responses, caused by microstructure changes,
porosity, microcracking, cracks, delaminations, fiber volume fraction,
velocity (elastic modulus), etc. |
|
Similar to a bonding evaluation, the resonance
behaviors in a multiple-layer material can be evaluated to solve a range
of unique NDT applications, such as thickness (or velocity, elastic modulus)
measurements of each layer, delamination detection, adhesive layer evaluation,
etc. |
