Numerical study of the center of gravity in the strengthening zone of steel with corrosion

In this paper, an unusual approach is used. The method of statistical mathematics is applied to determine the center of gravity in the strengthening zone in the stress-strain curve. The change of the center of gravity is numerically studied, and this part of the stress-strain diagram is represented as a function, respectively, it is divided into known figures, from which the center of gravity can be determined. Experimental measurements from corroded steel are utilized, and mathematical analysis is performed employing stochastic, average, and RMS techniques. Finally, the obtained results are presented, and it is noted that they also confirm that corrosion affects only strain and not stress on steel.
