Furthermore, we propose a numerical scheme for this kind of contact problems for Koiter shells and show numerical simulations after implementation by using the free software package FreeFem++.engCopyright © 2025, Sage Publications © The Author(s) 2025.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/ShellsMembraneKoiterContactAsymptotic analysisNumeelasticityDeformable foundationrical analysisNormal complianceConvergencejournal articleopen access10.1177/10812865251400629
