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.
