ASSOCIATED AND NON-ASSOCIATED FLOW RULES IN THE STRESS STATE PREDICTION
Vobejda R., Šebek F., Petruška J., Kubík P.
pages 512 - 515, full text

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 nonquadratic 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.
