With
the increasing use of Technical Justification in inspection
qualification and performance demonstration, increasing demand for the
inspection of complex geometry components and the application of
advanced inspection techniques such at PAUT and TOFD, recent
years have seen a rapid increase in the use of theoretical modelling of
inspection capability.
Properly validated theoretical models can be used for a number of
purposes related to inspection design and capability assessment.
In UT inspection of complex geometry components, models can be
used to generate volumetric coverage maps and to predict the amplitude
response of postulated defects of concern. Such information can be used
to technically justify inspection technique performance by
demonstrating that full coverage can be obtained and that defects of
concern will give above threshold amplitude responses. It can also be
used to guide technique selection and development.
KANDE has developed sophisticated mathematical models that can predict
the performance of pulse-echo and TOFD inspections in as-built complex
geometry components and can also be used with our InSight data display
and analysis software to reconstruct data in the component geometry.
Our AICT (Adaptive Inspection Code Technique) is a special development
of our general modelling service. AICT models the performance that can
be achieved using code based inspections, identifies any
weaknesses in the specified inspection for the defects of concern, and
suggests any additional scans necessary to achieve the required level
of performance.
