UPPER BOUNDS TO LOAD FOR PLANE STRAIN WORKING OF ANISOTROPIC METALS

The method of finding upper bounds to the load to work isotropic metals under conditions of plane strain using tangential velocity discontinuities is extended to include anisotropic metals. The theoretical foundations of the method are presented and three simple examples are given, followed by one which results in a solution identical to that given by the standard slip-line field approach. An approach for load bounding using isotropic slipline fields is suggested.
