Optimization of initial blank shape to minimize earing in deep drawing using finite element method Kishor, Naval; D Ravi Kumar (2002)Deep drawing of highly anisotropic sheets causes earing in the formed cup (formation of wavy edge at the top). In the present work, an attempt has been made to study this earing problem in deep drawing of cylindrical cups ...
