TLDR
In this paper, an axially symmetric frictionless contact problem between a nonhomogeneous elastic halfspace and a rigid base that has a small axisymmetric surface recess was studied.Abstract:
We study an axially symmetric frictionless contact problem between a nonhomogeneous elastic halfspace and a rigid base that has a small axisymmetric surface recess. We reduce the problem to solving Fredholm integral equations, solve these equations numerically, and establish a relationship between the applied pressure and the gap radius. We find and graph the effects of nonhomogeneity on the normal pressure, critical pressure and on the surface displacement.read more

Frictionless Contact Between a Rigid Indentor and a Transversely Isotropic Functionally Graded Layer
TL;DR: In this article, the relationship between the applied load P and the contact area is obtained by solving the mathematically formulated problem through using the Hankel transform of different order, and numerical results have been presented to assess the effects of functional grading of the non-homogeneous medium and the application load on the stress distribution in the layer as well as on the relationship of applied load and the area of contact.

An improved finite element scheme for elastic contact problems with friction
Hung-Sying Jing,Ming-Liang Liao +1 more
TL;DR: In this article, the compliance matrix of all the contact node pairs is used rather than the flexibility matrix of each body during iterations, which results in great savings in computer storage and computation time.

Receding contact problem involving large displacements using the BEM
J.A. Garrido,Antolín Lorenzana +1 more
TL;DR: In this article, a boundary element analysis of the two-dimensional contact problem between elastic solids involving large displacements is presented, which guarantees equilibrium and compatibility at the nodes in the final deformed configuration and allows us to deal with problems undergoing large displacement without changing the initial discretization of the boundary of the bodies.

Axisymmetric contact problem for an elastic layer and an elastic foundation
TL;DR: In this article, the axisymmetric problem of an elastic layer lying on a semi-infinite foundation is considered, where the layer is pressed against the foundation by a uniform clamping pressure applied over its entire surface and a uniform vertical body force due to the effect of gravity.
