We propose a model of partially healed crack in a solid body. In the region of restoration of the integrity of material, the surface energy is assumed to be different from its value in the intact material. We determine the efficiency of various schemes of healing of the plate weakened by a rectilinear through crack under the mode I and mode II conditions, as well as under the conditions of bending and combined bending with tension. We take into account the effect of crack closure under bending. The problem of interaction of partially healed defects is solved.
