Cracking of a functionally graded coating due to sliding contact with heat generation
Balcı, Mehmet Nurullah ; Dağ, Serkan; Yıldırım, Bora (2023-01-01)
In this work, the thermal contact problem of a rigid flat punch sliding over functionally graded material (FGM) coating with a surface crack is investigated. The surface of a homogeneous isotropic substrate is ideally coat...
Mechanics of moving contacts involving functionally graded multiferroics
Toktaş, Selim Ercihan; Dağ, Serkan (2023-01-01)
This article introduces solution procedures for moving contacts involving functionally graded multiferroic coatings. A moving rigid punch of a flat or a triangular profile is assumed to be in contact with a multi-layer med...
Computational elastodynamics of functionally graded thick-walled cylinders and annular coatings subjected to pressure shocks
Abeidi, Abdelrahim; Dağ, Serkan (2022-12-01)
A computational technique based on domain-boundary element method (D-BEM) is developed for elastodynamic analysis of functionally graded thick-walled cylinders and annular coatings subjected to pressure shock type of loadi...

Multi-layer model for moving contact problems of functionally graded coatings with general variations in physical properties
Toktaş, Selim Ercihan; Dağ, Serkan (2022-04-01)
This paper presents a multi-layer model for moving contact problems of functionally graded coatings whose physical properties have general spatial variations. The coating is assumed to be composed of an arbitrary number of...
Oblique surface cracking and crack closure in an orthotropic medium under contact loading
Toktaş, Selim Ercihan; Dağ, Serkan (Elsevier BV, 2020-10-01)
This article presents analytical methods for analysis of an inclined surface crack in an orthotropic medium subjected to contact loading. Governing partial differential equations are derived in accordance with plane theory...
Forced vibrations of functionally graded annular and circular plates by domain-boundary element method
Eshraghi, Iman; Dağ, Serkan (Wiley, 2020-08-01)
Axi-symmetric dynamic response of functionally graded circular and annular Mindlin plates with through-the-thickness variations of physical properties is investigated by a new domain-boundary element formulation. Three gov...
Moving contact problems involving a rigid punch and a functionally graded coating
Balci, Mehmet N.; Dağ, Serkan (Elsevier BV, 2020-05-01)
Frictional contact mechanics analysis for a rigid moving punch of an arbitrary profile and a functionally graded coating/homogeneous substrate system is carried out. The rigid punch slides over the coating at a constant su...
Domain-boundary element method for forced vibrations of fiber-reinforced laminated beams
Ahmed, Zubair; Eshraghi, Iman; Dağ, Serkan (Informa UK Limited, 2020-01-01)
A domain-boundary element method for forced vibration analysis of fiber-reinforced laminated composite beams is introduced. Utilizing static fundamental solutions as weight functions in weighted residual statements, govern...
