One of our department’s faculty members, Res. Asst. Kemal ERTUNÇ, presented his paper titled “Buckling Analysis of Clamped Cylindrical Shells Composed of Exponentially Graded Materials Resting on a Pasternak Elastic Foundation” at the International Congress on New Trends in Mechanics (ICNTM25) / 24th National Mechanics Congress.
The study investigates the buckling behavior of cylindrical shells composed of exponentially graded materials (EGMs) resting on a Pasternak-type elastic foundation. First, the fundamental relations of EG cylindrical shells were mathematically formulated, followed by the derivation of governing equations on the Pasternak foundation. By adopting suitable shape functions satisfying clamped boundary conditions, the Galerkin method was applied to solve the resulting partial differential equations. An analytical expression for the nondimensional critical external lateral pressure (NCELP) was obtained, minimized with respect to the buckling mode, and evaluated numerically. Comparative analyses were conducted considering both the presence and absence of the elastic foundation, as well as varying foundation parameters.
This research provides a significant contribution to the literature on the buckling of shell structures and offers new insights into soil–structure interaction for civil engineering applications. We sincerely thank Res. Asst. Kemal ERTUNÇ for his valuable contribution in representing our department at the international level.
