摘要：
Multistage incremental sheet metal forming (MS-ISF) is used to produce sheet metal parts with a large forming angle. Similar to the forming limit diagram (FLD) in stamping, FLD in MS-ISF is not sufficiently reliable due to the effect of loading path. To solve this problem, a method to calculate the forming limit stress diagram (FLSD) from FLD was proposed. Experiments proved that FLSD is a reliable fracture indicator that is unaffected by the loading path in MS-ISF.
