Statistical laws of fragmentation for wide range of load intensities are analyzed using the data of in-situ registration of fractoluminescence sequences and fragment mass distribution of recovered samples. The correlation between of temporal fractoluminescence sequences, statistical laws of fragment distribution and optical images of fracture surface morphology is discussed. © 2023 The Authors.

Introduction The problem of fragmentation represents fundamental and applied interest to provide the knowledge concerning condensed matter response, when the qualitative change of statistical laws reflects the global change of the defect induced symmetry properties and ability of energy absorption in the wide range of load intensity. Qualitative change of symmetry properties can be considered as pronounced sign of criticality of out- of equilibrium system “solid with defects” and the way of ranging quasi -brittle and ductile responses. This involves analyzing the behavior of the 27th International Conference on Fracture and Structural Integrity (IGF27) Scaling laws in fragmentation dynamics of ceramics and natural materials Irina A.
