An appraisal of Rankine and Perry-Robertson buckling formula under the combined effect of corrosion –shot peening interaction for 304 stainless steel alloy

Abstract

Seawater has been used to immerse metals in several industrial applications. Axial loading is applied to these alloys. These alloys are prone to corrosion failures due to differences in environmental conditions. This research looked at the influence of submerged corrosion on the buckling behaviour of 304 stainless steel long column type and intermediate alloy under increasing compressive dynamic stresses. Compressive buckling experiments were performed on twenty-four 304 stainless steel alloy columns, twelve of which were non-corroded, and the tests were performed under increasing axial dynamical compression loads. Before testing, the remaining columns were submerged for 90 days. For the subterranean columns, a maximum decrease of percent in critical buckling loading was obtained. This work uses the Rankine, and Perry-Robertson formulas to calculate the critical buckling stress of non-corroded and corroded 304 stainless steel alloys. The theoretical conclusions of the critical buckling stress were in good accord with experimental data
