Systems analysis and the behaviour forecast of metal constructions at repair the steel tanks, made by the method of rolling

In work the mathematical modeling of slam crack occurrence process in wall of repaired vertical steel rolling tank for storage the oil and oil products is described. Slam cracks in a tank wall arise at elimination of such defects as angularity, inadmissible deviation of walls forming from vertical, dents, elimination of not design constructive elements by a method of replacement of the part of a wall by sheets, flared to design radius of the tank, which do not have internal stresses.
