Radiographic Testing in CIVA Education

 

In CIVA Education RT, both direct radiation and first-order scattering radiation are computed for qualitative and fast but realistic simulations, in the following configurations:

  • Planar and Cylindrical component geometries, weld with 30° V-Beve
  • Material database including various steel alloys
  • Gamma-Ray isotopes: Co60, Ir192, Se75
  • X-ray source database of different energies (from 50 kV to 450 kV)
  • Argentic film database and photostimulable image plate detectors
  • ASTM Hole penetrameters and wire EN-IQI
  • Parallelepiped or spherical defects (void or inclusion)
  • Accounts for geometrical unsharpness
  • Photon paths display

 

Examples of simulations

Among many other ideas, the RT module of CIVA Education will help you to teach the following topic:

  • Visualize the impact of thickness change on the radiogram obtained

 

 

  • Highlight the impact of specimen materials on the photons path and the radiogram obtained

 

 

 

  • Clarify how scattering affects image quality, for instance by reducing contrast and increasing noise.

 

 

  • Illustrate the sensitivity of the RT technique depending on the defect orientation

 

 

  • Check the effect of the exposure time on the obtained level of density on the film

 

 

  • Evaluate the impact of the source orientation on a pipe component to locate the flaw
  • Understand the impact of geometrical unsharpeness and its origin
  • Illustrate the difference obtained with sources of different energy level
  • And many other phenomena!
