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...
Mechanics of dynamic contact of coated substrate and rigid cylindrical ended punch Balci, Mehmet N.; Dağ, Serkan (Springer Science and Business Media LLC, 2019-05-01) The dynamic contact mechanics of isotropic elastic coating bonded to homogeneous substrate was examined. The coating is indented by a sliding rigid punch of a cylindrical profile. The rigid punch moves over the coating at ...
Solution of the dynamic frictional contact problem between a functionally graded coating and a moving cylindrical punch BALCI, MEHMET NURULLAH; Dağ, Serkan (Elsevier BV, 2019-04-01) This paper presents an analytical method developed to investigate the dynamic frictional contact mechanics between a functionally graded coating and a rigid moving cylindrical punch. Governing partial differential equation...
Dynamic frictional contact problems involving elastic coatings BALCI, MEHMET NURULLAH; Dağ, Serkan (Elsevier BV, 2018-08-01) This paper presents a general theory of dynamic frictional contact of elastic coatings pressed against by a rigid punch moving with a constant speed. Governing equations of elastodynamics are solved by applying Galilean an...
Thermal effect on bending, buckling and free vibration of functionally graded rectangular micro-plates possessing a variable length scale parameter Aghazadeh, Reza; Dağ, Serkan; Ciğeroğlu, Ender (2018-08-01) Modified couple stress based model is presented to investigate statics, dynamics and stability of functionally graded micro-plates subjected to mechanical and thermal loadings. The features of FGM micro-plate including len...
Hyperbolic heat conduction based weight function method for thermal fracture of functionally graded hollow cylinders Eshraghi, Iman; Soltani, Nasser; Dağ, Serkan (2018-08-01) This article introduces a weight function method for fracture analysis of a circumferentially cracked functionally graded hollow cylinder subjected to thermal loads. The non-Fourier hyperbolic heat conduction model is used...
Modelling of graded rectangular micro-plates with variable length scale parameters Aghazadeh, Reza; Dağ, Serkan; Ciğeroğlu, Ender (2018-03-10) This article presents strain gradient elasticity-based procedures for static bending, free vibration and buckling analyses of functionally graded rectangular micro-plates. The developed method allows consideration of smoot...
