Abstract : Solutions are presented for several linear elastostatic boundary value problems pertaining to infinite bodies which contain holes or inclusions. The first two sections of the report consider planes which are loaded by normal stresses at infinity and contain a single perfectly smooth inclusion of circular or elliptic form. The third section is devoted to determination of stresses in an infinite plate having a doubly periodic rectangular array of holes which are either uniformly pressurized or contain rigid inclusions bonded to the plate. The principal stresses at infinity act in the directions of the rectangular grid and the holes are assumed to have symmetry axes in these directions. The final section of the report presents a solution for the axisymmetric stress field about two rigid spherical inclusions bonded to a surrounding infinite medium. The inclusions can be unequal in size and are arbitrarily spaced with two independent normal stress components specified at infinity. Numerical results were obtained for each problem studied. Programs written in FORTRAN II programming language are listed in appendices. (Author)
