This paper is concerned with a row of equally spaced equal elliptical holes or cracks in a plate subjected to transverse and longitudinal tensions. The analysis is based on the Laurent series expansion method combined with a perturbation procedure. Computations were carried out for various shapes, sizes and numbers of holes, and σ_<max> was represented as a dimensionless factor S_<max> based on the maximum stress σ_o for a single elliptical hole. This factor S_<max> corresponds to the dimensionless maximum stress intensity factor in the case of cracks. For any fixed shape and size of hole, S_<max> was shown to be linear with the reciprocal of the number of holes. The numerical results were fitted to convenient polynomial formulae. They give reliable values of S_<max> for arbitrary shapes, sizes and numbers of holes.
