Abstract

The subject of the present article is the stress concentration factors at a small circular hole in a large sheet of plastic anisotropy, subjected to equi-biaxial tension. In the present analysis an orthotropic yield function suggested by Hill and approximate solution technique developed by Durban are used. Numerical results for aluminum and copper sheets are presented.
