Twinning induced plasticity steels (TWIP) are very good candidate for automotive industry applications because they potentially offer large energy absorption before failure due to their exceptional strain hardening capability and high strength. However, their behaviour is drastically influenced by the loading conditions. In this work, the mechanical behaviour of a TWIP steel sheet sample was in...

this paper investigates the forming of sheet metal forming under cycling loading by considering the bauschinger effect. different proposed plasticity models which can handle this kind of deformation process have been reviewed in details. for instance, isotropic, kinematic and combined forms in the linear and non-linear cases including the well-known yoshida and chaboche's models have been ...

The increasing application of aluminum alloy, in combination with the growth complexity components, provides new challenges for numerical modeling sheet materials. material elastic–plasticity constitutive model is most important factor affecting accuracy finite element simulation. mixed hardening can more accurately represent real characteristics plastic deformation process, and property-relate...
