摘要：

Changes of stress intensity factors (SIF) of a flat main crack with rectilinear front which cuts the system of regular parallel pore channels normally to their direction are determined. Channels had cross-sections in the form of a circle, an equilateral triangle, a triangle with the concave sides of constant curvature and a starlike crack. It is shown that SIF on the main and channel cracks may have comparable values.
