- Abstract
- Experimental studies of the destruction processes of composite materials have been conducted, in particular, an analysis of acoustic emission, which show that the energy distribution of destruction events obeys a power law, which allows us to consider the accumulation of damage as a process of self-organized criticality (SOC). It has been established that 1/f noise is a characteristic feature of material degradation and can serve as an indicator of damage accumulation. A theoretical justification for these phenomena is presented in the context of self-organized criticality theory, proposing a discrete-time model in the form of a cellular automaton on a fractal structure simulating the granular environment of a composite. Temporal and spatial early warning signals associated with critical material deceleration during its self-organization into a critical state with avalanche-like failure dynamics are also presented.
