This paper considers the influence of interference between disk and hole on the stress and displacement distributions around a circular hole. which is filled with a smooth elastic disk, in an infinite elastic plate under uniaxial uniform tensile or compressive loading. The contact radial stress between disk and hole is expressed with absolute convergent series, whose differential form is also convergent. The stress and displacement are numerically analyzed by the point matching method. Numerical results are presented for various combinations of sizes and moduli of plate and disk. The main results are as follows: (1) The contact region and stress distribution of plate are independent of the magnitude of uniaxial loading, when diameters of disk and hole are initially the same. (2) When diameters of them are not the same, the contact region and stress distribution of plate vary with a change in magnitude of loading.
