Super-element S2 with non-linear asymmetric material characteristic for balls Super-element S3 is the consecutive modification of super-element S2.
FEM software defined optional non-linear materials for the truss element.
The method of modelling the rolling elements, which are replaced by special elements (super-elements), is the key stage in the presented computational methodology.

Thus, understanding the primary differences between the signals generated by these two different source classes is of key importance.
The WT results were obtained using the AGU-Vallen Wavelet freeware (Vallen, 2005) with the key parameter settings being: maximum frequency = 700 kHz; frequency resolution = 3 kHz and wavelet size = 600 samples.
Instead, it could be done on a plate or shell of the same thickness and material as the real structure.
