- Аннотация: The processes of transformation and interaction of defects such as the flat intergranu-lar microcracks under treatment electropulsing are investigated. Investigation on the basis of numerical coupled model of the impact of high-energy electromagnetic field on the pre-damaged thermal elasticplastic material with defects are carried out. The calculations has shown, that welding of the crack and healing of the micro-defects under the treatment of short pulse of current are took place. For the macroscopic description of the healing process the material healed and damage parameters are entered. The processes of change healed and damage parameters from the time under the action of current pulse are investigated. The questions about the choice of the preferred regions of integration in the modeling of these processes are considered. The effect of the mutual positions of microcracks and their shape on the change healed and damage over time are studied.
