Improving the operational and technological properties of industrial products, improving the technical level and quality of products is one of the main tasks of science and technology. The continuous tightening of requirements for the reliability of structural elements makes it necessary to analyze in more detail the specific conditions of their work. Most machine parts, machines and parts are subjected to cyclic loads during operation. Therefore, the problem of endurance of materials is relevant for railway, automotive, aviation, shipbuilding, machine tool, energy and other industries. In the present work, a new concept has been proposed to reduce the defective crack frames by making powerful reinforcing ribs. Thickened corner reinforcing ribs were made on the inner wall of the casting.
