Our Porosity/Inclusion Analysis provides a range of algorithms allowing porosity/inclusions to be located within the object and provides detailed information about these defects.Porosity or inclusions are color-coded in all 2D and 3D views of the data set. Detailed information about each individual defect such as its volume, projected size and position are provided in a table. By using the metrology data, this information can also be specified with the highest possible precision in any calibrated coordinate system. Statistical data about the overall object such as its porosity (in percent) or the sum of all defect surfaces complete this information. A porosity/inclusion analysis can be performed on an entire scanned object. Using the ROI concept, it is also possible to restrict such an analysis to relevant areas or to perform porosity/inclusion analyses using different parametes in different areas of an object. The results of a porosity/inclusion analysis can be compiled to create an inspection report, optionally including automatically generated or individually selected images. Features - automatic and fast detection, analysis and visualization of pores or inclusions in the material - volume, position, size and surface area are determined for every individual pore/inclusion - color-coding of pores or inclusions according to volume - defect size statistics, total percentage of porosity and pore volume histogram - analysis of the entire object or Regions of Interest - user-defined reporting of analysis results Porosity/Inclusion Analysis Features Locate pores, holes, and inclusions within parts and get detailed information on these discontinuities: - Detect, characterize, and visualize porosity in 2D and 3D using computed tomography. - Distinguish between gas pores, shrinkage cavities, cracks, and inclusions of foreign material. - Take wall thickness analyses and subsequent machining steps into account. - Automatically quantify the surface size of discontinuities in 2D CT slice images in accordance to BDG Reference Sheet P 201/P 202. (Extended Porosity/Inclusion Analysis Module) - Perform a 3D evaluation with regard to the most critical porosity parameters within functional areas of the part in accordance to BDG Reference Sheet P 203. (Extended Porosity/Inclusion Analysis Module) - Get results for later use in subsequent simulations. - Use data in statistical evaluation software such as Q-DAS qs-STAT. Global Porosity Parameters Determine these global porosity parameters for the entire component: - Total pore volume - Total material volume - Total porosity - Total surface of the pores - Projected total area of all pores in any spatial direction Properties of Individual Pores Determine these parameters for individual pores: - General: - Position - Deviation of gray values - Minimum, maximum, and average gray value - Size: - Volume - Surface - Equivalent diameter (diameter of a sphere with the same volume) - Radius or diameter of the circumsphere - Shape: - Compactness - Sphericity - Shape of fitted ellipsoid (from a Principal Components Analysis) - Projected dimensions: - Projected length in arbitrary spatial directions - Projected area in arbitrary spatial directions - Additional features: - Classification (inside, outside, or cut from the machined surface) - Minimum and maximum edge distance - Cut surface with component surface - Distance to next pore (gap) - Wall thickness at the location of the pore - Relative diameter (i.e., diameter of the pore relative to the local wall thickness)
