    Associated and non-associated flow rules in the stress state prediction

  • Original language description

    The paper deals with an application of the non-associated flow rule within a complex plasticity model. This leads to a significant improvement in the predicted stress state. The predicted stress state is closer to theoretical value on the contrary to the case when an associated flow rule – within quadratic or non-quadratic yield criteria – is used. The implementation of a more flexible plasticity model will be subject of a further study. The results suggest that the yield criterion has to be more versatile within Haigh–Westergaard space.
