Customers of NDE at NASA are increasingly interested in more detailed visualization and analysis of NDE data. To this end, NASA Glenn Research Center has made a significant cost and time commitment in evaluating open-source and commercial software packages, mainly for X-ray computed tomography (CT) slice viewing and volume rendering. Such software packages are becoming more powerful and user-friendly, especially as 64-bit operating systems allow users to work with gigabyte-sized data sets. With some of the software packages, the rendered volumes can be converted into solid and finite element models via novel meshing techniques. The latter extension of CT is an especially valuable method as it allows for further analytical and engineering modeling using the actual measured damage (for example, finite element modeling and analyses of thermo-mechanical loading conditions that the component might be subject to). Examples will be shown in the areas of X-ray computed tomography and waveform-based NDE. Emphasis is on methods that are most useful not only for the NDE professional analyzing the data but also for sharing of the data with customers such as material processors, testers, and modelers who need to use the data for various engineering decisions.
