The Contact Problem Between an Elliptical Punch and an Elastic Half Space with Friction : (The Case of the Punch Subjected to Moment)

Abstract

This paper is concerned with the complete adhesion problem when an elastic half space is subjected to moment by an elliptical rigid punch. By using Abel transform, we reduce the problem to solve the inhomogeneous simultaneous Hilbert problem with infinite unknown functions. A general method for solving the problem is given. Numerical results are shown for the distribution of contact stresses and surface displacements in several cases of the punch aspect ratio.
