CIVA Modelling
CIVA Modelling reduces the time required for on-site testing and increases the reliability of the tests.
Advantages
Applications modelling can be used for the following:
- Prediction and visualisation of ultrasonic field
- Calculation of focal points
- Prediction of the interaction of ultrasound with flaws of various types
- Verification of the behaviour of ultrasound in components of complex geometry (e.g. pressure vessel nozzles)
- Removal of expensive, timely validation activities
- Enhanced imagery to assist with the understanding of ultrasonic beam propagation
Global NDT Consultants Approach
Development and evaluation of inspection approaches for specific applications which typically cover complex geometries where beam paths and profiles would be difficult to assess. A range of ultrasonic inspection approaches can be modelled including single-probe compression and shear-wave pulse-echo, twin-probe "pitch-catch" arrangements, Time of Flight Diffraction and Phased Array Inspection.
Simulations on coarse-grain structures can be done by creating volumes with the help of Voronoï diagrams. This model reproduces the beam deviation phenomena typical of coarse-grain structures such as cast stainless steel.
