The authors would like to thank Prof. Gresnigt for reading their paper and for preparing an extensive commentary, which addresses interesting issues stemming from his long-time experience in pipeline mechanics and behavior. It is the authors’ opinion that his commentary identifies several demanding problems on this subject and can be used as guidance for future research work. Our closure is aimed at complementing the commentary in further discussing those issues.

In the course of our study, we examined several parameters that affect buckling behavior of confined thin-walled cylindrical shells. Nevertheless, a few additional parameters are stated by Prof. Gresnigt, namely residual stresses, Bauschinger effect, and heat treatment that may influence the mechanical properties. Residual stresses and the Bauschinger effect are mainly related to the manufacturing process. For large-diameter, thin-walled cylinders (D/t > 100), the most popular manufacturing method is spiral welding of...
