摘要：

In the present work the recently introduced Joined Ductile Failure (JDF) model has been slightly improved and is applied to sheet forming of an AA5182 aluminium alloy. Despite its simplicity the validation examples documented in the present work reveal that the JDF model is able of accurately predicting the onset as well as the location of ductile failure.
