Abstract
A bridged crack model is used to evaluate the effectiveness of cracks self-healing. During the self-healing process the following stages should be analyzed: 1) flaws/cracks formation and growth under external loading; 2) activation of self-healing mechanisms; 3) healing of flaws/cracks with partial or complete restoration of bonds between cracks surfaces. The kinetic model is used to estimate the formation time of the crack bridged zone. The decreasing of the stress intensity factors is considered as the main characteristic of a crack self-healing efficiency.
