Analytical Expression

Based on earlier works by the authors an analytical expression for the surface temperature of a halfplane heated by fast moving rolling/sliding contact and cooled by convection on the surface of the halfplane is presented by applying the Laplace transformation technique and the solution of a Volterra integral equation of the second kind.

Class Of Functions

We consider quasi-static contact problem on frictional heating on a sliding contact of a rotating rigid cylinder and a half-plane. The cylinder is pressed towards the half-plane material. The problem is reduced to solution of a singular integral equation with respect to contact stresses. Solution of the singular equation is looked for in a class of functions limited on the edge, with two additional conditions to determine timedependent boundaries of the contact area. Temperature at the contact and inside the half-plane is determined in terms of contact stresses.

Practical Implications

The problem of plane elastic contact between a symmetrical indentor and a half-plane is addressed. The form of the contacting profile of the indentor is represented in terms of Chebyshev polynomials, and the resulting stress-field is deduced, for both static and sliding contact. It is shown that by making the profile somewhat flatter than a cylinder a large load may be sustained without yielding. Practical implications of the result, including profiles needed to attain optimal contact conditions, are discussed.

Material Mismatch

Closed-form expressions for the contact pressure between a blunt wedge and an elastically dissimilar half-plane are presented. It is demonstrated that for practical values of the material mismatch parameter, β, and coefficient of friction, f, the results do not differ significantly from the elastically similar problem.
