Fig. 4. The application of Eq.(1) as a fitting function (red solid curve) on the dataset of cumulative energy released (blue solid curve) for both cases of AE (upper graph) and PSC (lower graph). As a black dotted curve it is shown the corresponding application of a simple power law with no log-periodic corrections for each case.

possibilities of studying the deformation procedure of a material and extracting useful conclusions of the fracturing phenomena of a material and structures in general.
