Abstract
In a previous paper by the author (1), a theoretical solution for an infinite strip with a circular hole under plain bending is given by the method of successive approximation. This method demands laborious calculations. However, it seems that the labor can be diminished by employing the method of perturbation. In this paper, the effect of a circular hole in an infinite strip under the state of pure twist is investigated with the help of the perturbation method. The maximum deflections on the rim of the hole and the maximum stress couples in the strip are calculated and plotted versus hole-diameter strip-width ratio and Poisson’s ratio of the plate material. Here the strip is considered subjected to the limitation of the Poisson-Kirchhoff theory of bending of thin plates.
