Fig. 7. – Multifractal spectra constructed for cluster 1 (red), for cluster 2 (blue) and for the entire set of points (black) dependences ε (t) for woven composites with a stress concentrator under uniaxial quasi-static (a) and cyclic (b) loads

When comparing the results of the data analysis on the distributions of fluctuations of deformation fields obtained under quasi-static and cyclic loading of unidirectional and woven polymer composite samples with a hole, general patterns become visible. Specifically, two clusters emerge, which are consistent with the results of
