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 along the boundary between the inserted plug and the hole. The contact pressure between the inserted plug and the hole is expressed in a convergent series whose differntial form is also convergent, so that the stressd and displacement generated along the boundary can be numerically analyzed by the pointmatching method. Using the numerical results for various elliptic shapes, the influence of interferencs is shown with the stress around an elliptic hole.
