Abstract Scope |
Many of the non-destructive testing technologies developed for the evaluation of pre-baked carbon anodes are based on measurements representing the response of the material contained along a specific pathway in their bodies. To assess anode homogeneity based on these data, some ways of interpolating the measurements within the anode volume are required. This paper presents a method to interpolate such measurements to estimate the distribution of properties at different points within an anode’s body, such as the speed of sound. The method is demonstrated first by testing it using a set of 2- and 3-dimensional toy examples, and then on a few full-scale anodes tested using acousto-ultrasound measurements. The resulting interpolations are cross-checked with the presence of external defects. The technique is suitable for understanding the level of isotropy, positioning defects and also enhancing the probes design for future implementation of NDT techniques. |
