Abstract

This paper is concerned with the mixed boundary value problems of an infinite plate with an elliptic hole. Into which a smooth rigid elliptic plug is simply inserted. Since the infinite plate is subjected to a uniaxial loading (tension or compression) at infinity, apertures are produced in parts along the boundary between the inserted plug and hole. The contact pressure between the inserted plug and the hole is expressed in a convergent series whose differential from is also convergent, so that the stress and displacement generated along the boundary can be numerically analyzed by the point matching method. Using the numerical results for various elliptic shapes, the influence of interference is shown with the stress around an elliptic hole.
