Assoc. Prof. Ferruh Turan

He received his B.Sc. degree from the Department of Civil Engineering at Ondokuz Mayıs University (OMU) in 2011. He completed his M.Sc. studies in Civil Engineering at the Graduate School of Natural and Applied Sciences of OMU in 2014. In 2020, he earned his Ph.D. degree in Civil Engineering from the Graduate School of Graduate Studies at OMU with a dissertation entitled “Investigation of the Geometrically Nonlinear Forced Vibration Problem of Functionally Graded Ortho­tro­pic Spherical Shells Using Shear Deformation Shell Theory.”

He began his academic career as a Research Assistant at the Graduate School of Natural and Applied Sciences in 2012 and was appointed as an Assistant Professor in 2021 at the Faculty of Engineering of OMU. He is currently serving as an Assistant Professor in the Mechanics Division of the Department of Civil Engineering at the OMU Faculty of Engineering.

Scientific Research

His research interests include:

1. Structural Mechanics: Plate and shell theories, stability theory, nonlinear forced vibration theory

2. Innovative and Smart Materials: Functionally graded materials, carbon nanotubes, porous materials

His scientific work primarily focuses on investigating the structural behavior of plates and shells composed not of classical materials but of advanced material systems such as laminated composites, functionally graded materials, carbon nanotube–reinforced composites, and porous composites. All models are analyzed using classical or higher-order shear deformation theories.

His research in structural mechanics is mainly centered on the analysis of plate- and shell-type structural components made of composite materials. Shell structures play a significant role in civil, aerospace, and marine engineering due to their superior properties and advantages. These include exceptional load-carrying capacity, high strength and stiffness, excellent resistance under external loads, and high strength-to-weight ratios, making them vital in architectural, structural, defense, aerospace, and space engineering applications.

Shell-type structures are inherently three-dimensional solids whose behavior can be described by elasticity theory. However, full 3D formulations require a large number of degrees of freedom and are computationally expensive. Therefore, the original 3D problems are simplified into more manageable forms using appropriate hypotheses—namely, classical shell theory and shear deformation theories.

With advancements in material science, increasing attention has been given to innovative materials such as functionally graded materials (FGMs), whose properties vary continuously through the thickness of plates and shells. His research investigates the effects of different FGM profiles on natural frequencies, nonlinear free and forced vibration characteristics, and static and dynamic stability responses of structural components.

Carbon nanotube-reinforced composites represent another class of advanced materials studied in his work. These materials aim to enhance the mechanical behavior of structural components—especially stiffness and strength—by embedding nano-sized reinforcements within the material system.
