Almtract--A new, simple and practically applicable equation, including the normal anisotropy value R and the strain hardening exponent n, for estimating the limiting drawing ratio LDR in cup-drawing of a cylindrical cup with a flat-nosed punch is derived. The normal anisotropy is based on Hill's the
