Numerical analysis of a contact problem with wear [PDF]
Computers and Mathematics With Applications, 2020 This paper represents a sequel to the previous one, where numerical solution of a quasistatic contact problem is considered for an elastic body in frictional contact with a moving foundation. The model takes into account wear of the contact surface of the body caused by the friction. Some preliminary error analysis for a fully discrete approximation of

Determining a Surrogate Contact Pair in a Hertzian Contact Problem. [PDF]
J Tribol, 2011 Laboratory testing of contact phenomena can be prohibitively expensive if the interacting bodies are geometrically complicated. This work demonstrates means to mitigate such problems by exploiting the established observation that two geometrically dissimilar contact pairs may exhibit the same contact mechanics.

Mathematics, 2022 A new type of non-classical 2D contact problem formulated over non-convex admissible sets is proposed. Specifically, we suppose that a composite body in its undeformed state touches a wedge-shaped rigid obstacle at a single contact point.

Multidimensional Contact Problems in Thermoelasticity [PDF]
SIAM Journal on Applied Mathematics, 1998 Summary: We consider dynamic and quasi-static thermoelastic contact problems in \({\mathbb R}^n\) modeling the evolution of temperature and displacement in an elastic body that may come into contact with a rigid foundation. The existence of solutions to these dynamic and quasi-static nonlinear problems and the exponential stability of the solutions are

Characterization of the Functionally Graded Shear Modulus of a Half-Space
Mathematics, 2020 In this article, a method is proposed for determining parameters of the exponentialy varying shear modulus of a functionally graded half-space. The method is based on the analytical solution of the problem of pure shear of an elastic functionally graded ...
