ИСТИНА

The process of materials self-healing is considered as kinetic formation of bridged zones of cracks. In the crack bridged model it is assumed that the tractions that prevent a crack opening reduce the stress intensity factors, but the stress singularity at the crack tip is preserved. As the main characteristic of cracks self-healing efficiency is used the decreasing of the stress intensity factors as the crack bridged zone is formed . The mathematical background of the problem solution is based on the singular integral-differential equations. The analysis of the cracks self-healing processes at the different materials interface with the adhesive layer having the effect of self-healing is presented.
