- •
Quasi-unilateral and shear extensions are introduced to the uncoupled version of Lemaitre’s damage model as new fracture criteria.
- •
Implications of the extensions in forming process simulation practice are underlined.
- •
Closed form solutions are supplied for linear strain paths complemented with fracture surface plots in various spaces.
- •
Validation studies are realized using various experimental results available in the literature.
- •
Results are compared with those of various fracture criteria.
