This paper analyzes the sliding frictional nanocontact of an exponentially graded layer perfectly bonded to a homogeneous half-plane substrate under the nanoindentation of a rigid cylinder. The punch is subjected to both normal and tangential loads, satisfying Coulomb’s friction law. The contact interface is modeled by the full version of Steigmann...

This paper considers the receding contact problem between an exponentially graded layer and a homogeneous layer under the indentation of a tilted rigid flat-ended punch. In the presence of an offset load deviated from the symmetry axis of the rigid punch, the contact pressures both under the rigid punch and along the receding contact interface betw...

This paper solves the frictionless receding contact problem between a graded and a homogeneous elastic layer due to a flat-ended rigid indenter. Although its Poisson’s ratio is kept as a constant, the shear modulus in the graded layer is assumed to exponentially vary along the thickness direction. The primary goal of this study is to investigate th...

This paper solves the frictional receding contact between a functionally graded elastic layer and an orthotropic substrate under the indentation of a rigid flat-ended stamp. Both normal and tangential indentation forces, satisfying Coulomb's friction law, are considered. The shear modulus of the graded layer is assumed to vary exponentially along t...
