Analysis of the Initial Corrosion Stage of a Steel Disk Under the Influence of Stress

2020 
As known, there are many types of metals corrosion, which in turn leads to the appearance of cracks, which bring the details of mechanical engineering out of operation. The work investigates the corrosion of an isotropic stress disk. To analyze the effect of corrosion on the disk operation, the method of singular integral equations is used. We conducted a literature review of this topic. We showed the solution of singular integral equations. The asymptotic stress values of an isotropic medium with a corrosion crack in the field of centrifugal forces are obtained. The analysis of the stress state of an isotropic steel disk was carried out depending on the shape, size, and location of the damage. The problem of a fixed disk with a crack, which shores are loaded with normal pressure, is considered. We built graphical illustrations that confirm the dependence of cracks appearing on the load, and also prove the compensation of load by increasing the number of cracks.
