Method of consecutive approximations in the problem of rational distribution of porosity at the pure bend of the bar of rectangular section

This article is devoted to a task of rational distribution of porosity on bar section in case of a net bend. The solution of such task will allow to provide the necessary bearing capability in case of decrease in a material capacity of a design. A research purpose is to pick up the rational distribution law of porosity for the rectangular section of a bar in case of technical restrictions of production.
