On displacement fields in orthotropic laminates containing an elliptical hole

The classical Savin solution for the stress induced in an orthotropic plate containing an ellipitical hole places no restrictions on remote rigid-body rotations. In this paper the Savin procedure is used to obtain a solution for which remote rigid-body rotations are required to be zero. The validity of these new results is demonstrated by comparing predicted displacement f ields near a circular hole in specially orthotropic composite panels with t hose measured using moire techniques as well as those predicted using the f inite element method.
