This paper presents an analycal solution for an infinite strip having a symmetrically-located circular hole or a circular inclusion, where the strip is subjected to a bending moment at infinity. On the inclusion problem, two types of inclusions, i.e., perfect bonding and pure sliding are analyzed. The analysis is based on the Papkovich-Neuber stress function approach and the solution is obtained through a combination of harmonic functions of integral forms and infinite series. The boundary conditions at the interface of the strip and the inclusion are satisfied using the relations between the polar and Cartesian harmonics. The numerical results obtained from the proposed methods are illustrated the various stiffness ratios and sizes of the inclusion. The validity of the present solution is verified by comparing the theoretical results of Howland or Udoguchi.
