Stochastic damage evolution in brittle materials is analyzed with application of various scaling characteristics. Both temporal and spatial randomness of the process are studied. Characterization of a complicated morphology of failures is carried out in terms of a fractal approach. Effect of stochasticity extent on fractal dimension of failures and on load distribution near them is analyzed. Temporal scaling is investigated by means of transition to stochastic kinetic equations for damage accumulation. Three various type of temporal stochasticity (different variants of noise action) are studied. Introduction of a local failure criterion leads to estimation of time-to-fracture distributions under various types of stochastic action. Specific features of evolution of two different damage modes are discussed.
