| Abstract |
We consider an electrodynamical action taking account of the microdefects developing in the material. We study a material consisting of periodically distributed representative elements containing defects of different type (cylindrical microvoids, plane microcracks). The main result of this study is: we have found that microdefects are close and healed when electric current is run through the material and thermal stresses localize between defects,
which results in hardening of the material. Furthermore, as increased temperature localizes near the tips of microcracks, outmelting of the material takes place leading to increasing material porosity. The obtained results explain the mechanism of variation of the material properties under the action of electric field and can be used to develop equations of a coupled thermal electroplastic model of the material. |
