This work investigates the mechanical behavior of thin-walled tubes that werepreviously ovalized and subsequently subjected to internal pressurization. The analysisrevisits the experimental study conducted by Soares (2016) and incorporates additionalresults from the article Experimental study of ovalized thin-walled pipes (2025), whichexpanded the understanding of the phenomenon through numerical simulations.Ovalization, a geometric imperfection that alters the circularity of the cross-section, iscommon in industrial pipelines and can significantly modify the stress and strain stateunder internal pressure. To characterize this behavior, two experimental techniqueswere employed: Digital Image Correlation (DIC), which provides full-field strainmeasurements, and electrical strain gaging, which enables high-precision localmeasurements. The experimental data were compared with analytical predictions basedon the BS 7910/API 579 standard and the classical formulation of strength of materials.The experimental results showed good consistency and indicated a progressivereduction in eccentricity with increasing internal pressure, a trend also captured by theanalytical and numerical approaches. The discrepancies observed - especially in thelongitudinal strains - reflect simplifying assumptions present in analytical models andthe conservative nature of normative methodologies. Finite element simulations furtherdemonstrated that small geometric variations in the ovalization significantly influencethe structural response.The findings highlight the importance of integrating experimental measurements,analytical formulations, and numerical models to achieve a more realistic assessment ofthe structural integrity of ovalized tubes, particularly in scenarios involving complex ornon-elliptical imperfections.
