Buckling of rectangular FSDT plates resting on orthotropic foundation by mixed FEM
Kutlu, Akif; Omurtag, Mehmet Hakkı (Yıldız Technical University, 2020)This study presents a mixed type finite element procedure for the linear buckling analysis of moderately thick plates lying on orthotropic elastic foundation. Kinematical expressions are due to the Mindlin plate theory and ... -
Contact problem between a rigid punch and a functionally graded orthotropic layer resting on a Pasternak foundation
Çömez, İsa; Omurtag, Mehmet Hakkı (Springer, 2021)The present work is a pioneering study on the contact mechanics including Pasternak foundation model. The context of this research is frictionless plane contact problem between a rigid punch and a functionally graded ... -
An exact elasticity solution for monoclinic functionally graded beams
Çömez, İsa; Arıbaş, Ümit Necmettin; Kutlu, Akif; Omurtag, Mehmet Hakkı (Springer Heidelberg, 2021)In this study, an elasticity solution is presented for monoclinic functionally graded beams subject to a transverse pressure distributed sinusoidally. Monoclinic material properties are assumed to vary exponentially ... -
Forced vibration analysis of composite-geometrically exact elliptical cone helices via mixed FEM
Arıbaş, Ümit Necmettin; Ermiş, Merve; Kutlu, Akif; Eratlı, Nihal; Omurtag, Mehmet Hakkı (Taylor & Francis Inc, 2022)In this pioneering study, the cross-sectional warping included transient response and normal/shear stress components of composite elliptical and elliptical cone helices over exact axis geometry are investigated using a ... -
Free vibration of axially FG curved beam on orthotropic Pasternak foundation via mixed FEM
Ermiş, Merve; Kutlu, Akif; Eratlı, Nihal; Omurtag, Mehmet Hakkı (Springer Science and Business Media Deutschland GmbH, 2022)The main objective of this study is to present an accurate and consistent original formulation to describe the interaction between planar straight/curved beam structure and orthotropic foundation by highlighting the ... -
The static and free vibration analyses of axially functionally graded elliptical beams via mixed FEM
Ermiş, Merve; Akdoğan, Gökay; Kır, Oğuzhan; Arıbaş, Ümit Necmettin; Omurtag, Mehmet Hakkı (Golden Light Publishing, 2022)The objective of this study is to investigate the behavior of the static and free vibration analyses of axially functionally graded elliptical planar curved beams using a mixed finite element method (MFEM) based on the ... -
The static and stress analyses of axially functionally graded exact super-elliptical beams via mixed FEM
Arıbaş, Ümit Necmettin; Ermiş, Merve; Omurtag, Mehmet Hakkı (Springer, 2021)In this paper, the static response and normal/shear stresses of axially functionally graded exact super-elliptical beams are presented via a warping-included mixed finite element method. Super-elliptical axis geometry is ... -
Two-dimensional solution of functionally graded piezoelectric-layered beams
Çömez, İsa; Arıbaş, Ümit Necmettin; Kutlu, Akif; Omurtag, Mehmet Hakkı (Springer Science and Business Media Deutschland GmbH, 2022)This study presents an exact elasticity solution for the functionally graded piezoelectric beams subjected to sinusoidally distributed transverse electromechanical loads. The elasticity solution can reflect the symmetrical ...
