Scientific-Technical Section


Various mechanisms of main crack propagation in a polycrystalline material are examined on the basis of a previously proposed numerical model of the microstructure. Intergranular macrocrack growth in the presence of microcracks in part of intercluster boundaries is examined in the plane case, whereas the mixed failure including intergranular or transgranular propagation of the macrocrack in relation to the cracking resistance value is examined in the spatial case. The effect of elements of the microstructure (microcracks and voids) on the strength characteristics of the material is determined.
