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...
