چکیده انگلیسی
Commonly finite element analysis uses hypoelastoplastic (HEP) formulation to simulate forming processes and springback. In this study an elastoplastic (EP) formulation in finite strains is used. In the case of large elastic domain it has been found that the HEP law leads to oscillatory responses in shear test. Furthermore we show that the use of this law in springback simulation needs many increments to obtain an accurate solution. Alternatively, the use of an EP law gives a non-oscillatory solution in shear test and it needs a few numbers of increments in springback simulations to obtain accurate results.
