Tóm tắt

The δ c -model of a crack-containing elastoplastic body was used to specify parameters that influence the healing of crack-type defects by filling them with the other material. The relationships are derived, which can predict the extent of crack-containing body strength recovery with various fillings. The “characteristic distance” of crack (filled or free) growth is established, when the intensity of external loads reaches its limit. It is shown that this distance is the constant of the material for unfilled macrocracks and constitutes a certain portion of the plastic zone formed near the defect.
