Abstract：

The forming limit diagram (FLD) is an important performance measurement for sheet metal. An investigation was made to obtain the FLD at the same time of cupping test. Through tesing on 20A steel sheet, 5A02O aluminum sheet and 1Cr18Ni9Ti stainless steel sheet, it is found that the distribution of the limit strains agrees well with FLD obtained through bulging test but there is a little shortening on the range of strain.
