On the Plane Stress Problem in a Ring of Orthotropic Material

Abstract

In the present paper, the two-dimensional stress distribution in an orthogonally aeolotropic plate, bounded by two concentric circular contours, is treated by the perturbation method using the orthogonal co-ordinates, similar to that of the previous papers. Numerical examples are worked out for three kinds of material, oak, plywood and isotropic plate. The results show that considerably large stress concentration may occur in some aeolotropic plates even in the case of uniform inner pressure.
