Discover what’s below the surface of your scanned parts. The porosity/inclusion analysis features in Volume Graphics software enable you to detect, characterize, and visualize porosity and inclusions in three dimensions using non-destructive testing (NDT).
Locate pores, holes, and inclusions within parts and get detailed information on these discontinuities:
In addition to the calculation and tolerancing of porosity parameters, you can easily display dependencies between porosity variables using suitable graphical representation in y-x plots. For example, a plot of the sphericity against the equivalent diameter may show that the larger pores are shrinkage holes, which can be identified by their lower sphericity.
The distribution of the values of a corresponding parameter can be displayed using histograms. The following example shows that the majority of discontinuities are characterized by a small relative diameter. Those with a relative diameter close to one will be considered critical, since the spatial extent and the minimum wall thickness in the area of the pore are in the same order of magnitude.
Since not only single discontinuities are crucial for component stability, Volume Graphics software also offers the opportunity to investigate porosity accumulations and their effects in more detail.
Besides calculating local porosity and local concentrations, it is also possible to map porosity in cells of volume meshes. Regular meshes can be used as well as volume meshes adapted to the CAD or the real surface.
The Porosity/Inclusion Analysis Module supports three of the most important guidelines for porosity analysis in order to make evaluations for cast parts easily understandable and reproducible: BDG Reference Sheets P 201, P 202, and P 203.
Manual and automatic image generation:
Detect particles within your part. The analysis of discontinuities can refer to the absence of material—the classic pore/voids analysis—as well as the presence of foreign particles.
With Volume Graphics software, you can detect unwanted contamination, such as in cases of machine wear, or explore the intended accumulation of added functional particles, such as metal flakes inside an insulator. All parameters that have been mentioned for porosity can also be determined for inclusions.
