    Abstract

    The measurement of residual stress using the deep hole drilling method relies on the evaluation of the distortion of a hole in a plate under the action of far-field direct and shear stresses. While closed form solutions exist for isotropic materials, in previous work for orthotropic materials finite element analysis has been used to find the distortion. In this technical note, Lekhnitskii’s analysis is used to find closed form solutions for the distortion of a circular hole in an orthotropic plate. The results are compared with those of finite element analysis for a range of material properties with excellent agreement.
