The top of the layer is subjected to normal tractions over a finite segment. The graded layer is modeled as a non-homogeneous medium with a constant Poisson’s ratio and exponentially varying shear modules. The problem is converted into the solution of a Cauchy-type singular integral equation in which the contact pressure and the receding contact half-length are the unknowns using integral transforms. The singular integral equation is solved numerically using Gauss–Jacobi integration. The corresponding receding contact half-length that satisfies the global equilibrium condition is obtained using an iterative procedure. The effect of the material non-homogeneity parameter on the contact pressure and on the length of the receding contact is investigated. © 2016, Springer-Verlag Wien.eninfo:eu-repo/semantics/closedAccessMathematical transformationsCauchy-type singular integral equationContact pressuresEquilibrium conditionsFinite segmentsFunctionally graded layersIntegral transformReceding contactSingular integral equationsIntegral equationsMathematical transformationsCauchy-type singular integral equationContact pressuresEquilibrium conditionsFinite segmentsFunctionally graded layersIntegral transformReceding contactSingular integral equationsIntegral equationsArticle22761753176610.1007/s00707-016-1580-y2-s2.0-84960416174Q2WOS:000376658900015Q2
