In the UT module, two types of computation are available: beam computation and inspection simulation.
3D Beam Computation
The features of the UT beam computation module are:
- Planar and Cylindrical component geometries, one weld example
- Isotropic material, one anisotropic example
- Contact or Immersion testing
- Conventional single element probes and linear PA (limited to 28 elements) probes
- Focused probe available for immersion testing
- Point focusing or beam steering with delay laws (for PA probes)
- Accounts for L waves, T waves and mode conversions
Examples of simulations
In UT, among other possibilities, the beam module of CIVA education can help you to illustrate the following phenomena:
- Visualize and characterize the main parts of the beam for a given probe (near field, far field, location of the maximum, beam sport size, etc.).
- Visualize the beam propagation, especially when specific phenomenon occur (propagation in an anisotropic material, grating lobe phenomena with a Phased-Array Probe).
- Understand and see the effects of focusing or beam steering.
- See the impact of the material velocity on the beam angle.
- Visualize the impact of physical parameters such as the probe frequency on the radiated beam.
- Evaluate the sensitivity zone of a separate T/R probe (such as TOFD or Tandem) with the combination of the emitted beam and the zone of sensitivity in reception.
- And many other possibilities…
2D inspection simulation for qualitative and fast computations
The inspection simulation module includes the following capabilities:
- Planar and Cylindrical component geometries, one weld example
- Isotropic material
- Contact testing
- Conventional single element probes and linear PA (limited to 28 elements) probes
- Pulse Echo, TOFD, Tandem
- Point focusing, beam steering, sectorial scanning with delay laws (PA probes)
- Simulations with planar and SDH flaws with various dimensions, locations and orientations
- Accounts for L waves, T waves and mode conversions
Examples of simulations
In UT, among other possibilities and ideas, the inspection simulation module of CIVA Education can help you to illustrate the following points:
- The different types of echoes scattered by an indication or by the component boundaries (diffraction, reflection, corner effect, etc.).
- Identify the different modes and for instance mode conversions phenomena.
- Illustrate the different UT techniques (Straight beam, Angle beam, TOFD, Tandem, PhasedArray...).
- Show calibration block set up to obtain DAC like curves.
- Understand beam spot sizing technique such as the 6dB drop one or using the tip diffraction signals.
- Show the impact of influential parameters on the signal sensitivity (such as flaw location and orientation, or probe parameters...).
- Etc.
