Modeling the stress-strain state of a circular plate subject to general corrosion according to various models

Quite a lot of works have been devoted to the problem modeling behavior thin-walled structures exposed an aggressive environment leading corrosive wear their surface. Researchers proposed fairly large set models wear, taking into account influence various factors on kinetics corrosion (time, material, temperature, nature environment, stress-strain state structure). Moreover, different authors often propose for same conditions. In article under consideration, rather unique comparative study three by (Dolinsky V.M., Gutman E.M., Ovchinnikov I.G.) was carried out simulate circular plate subjected combined action load and tear. identification models, that is, determination coefficients included in them, using experimental data. These were then used plates subject loads. The results numerical simulation compared with data obtained during testing plates. Interestingly, used, effect stress taken invariants state: intensity V.M. Dolinsky, medium voltage model E.M. Gutman, specific energy I.G. Ovchinnikov. analysis showed difference from experiment when considered does not exceed 9.3%. discrepancy between is also within acceptable range, which suggests all can be predict However, it interest conduct research predictive capabilities forecast arms go beyond scope studies. At time, carrying experiments complex stressed several allow good description most complete consideration operating conditions, makes possible obtain more versatile picture what happening design processes, comparison calculations performed according one model, even if describes well.
