The layers have different thicknesses and elastic constants. The normal and tangential forces are applied to the upper layer with a rigid cylindrical punch, and the lower layer is fully bonded to a rigid substrate. Poisson's ratios are taken as constant, and elasticity moduli are assumed to vary exponentially through the thickness of the layers. With the use of Fourier integral transform, the plane contact problem is reduced to a singular integral equation in which the unknowns are the contact pressure and the contact width. The singular integral equation is solved numerically using Gauss-Jacobi integration formula. The effect of several geometrical and physical parameters such as the material inhomogeneity, the friction coefficient, the layers' height, the mismatch in the material properties at the interface, and the contact width on the contact stress and in-plane stress are investigated in detail. en_US dc.language.iso eng en_US dc.publisher Springer Wien en_US dc.rights info:eu-repo/semantics/closedAccess dc.subject Frictional contact en_US dc.subject Elastic properties en_US dc.subject Layer-substrate en_US dc.subject Half-space en_US dc.subject Coatings en_US dc.subject Indentation en_US dc.subject Gradients en_US dc.subject Mechanics en_US dc.subject Solids en_US dc.subject Plane en_US dc.title The contact problem of a rigid punch sliding over a functionally graded bilayer en_US dc.type article en_US dc.relation.journal ACTA Mechanica en_US dc.contributor.department TOBB ETU, Faculty of Engineering, Department of Mechanical Engineering en_US dc.contributor.department TOBB ETÜ, Mühendislik Fakültesi, Makine Mühendisliği Bölümü tr_TR dc.identifier.volume 228 dc.identifier.issue 6 dc.identifier.startpage 2237 dc.identifier.endpage 2249 dc.contributor.orcid http://orcid.org/0000-0002-1159-556X dc.identifier.wos WOS:000401920000016 dc.identifier.scopus 2-s2.0-85014899791 dc.contributor.tobbetuauthor Güler, Mehmet Ali dc.contributor.YOKid 19122 dc.identifier.doi 10.1007/s00707-017-1827-2 dc.relation.publicationcategory Makale - Uluslararası Hakemli Dergi - Kurum Öğretim Elemanı tr_TR
