Ductile fracture in AA5083 sheet depends on temperature and strain rate sensitivity.
AA5083 rupture mechanism at room temperature is by critical shear stress when M=0.
Local necking at sheet surface leads to limit strains at high temperatures when M>0.
D-Bressan and M-K models were presented with good correlation with experimental FLC.
Both models can be applied to linear and non-linear strain path.
