Original Abstract

The paper deals with the application of non-associated flow rule to the nonquadratic yield criterion. The utilization resulted in a significant improvement in the predicted stress states as well as deformations, which matched the theoretical values and experimental observations. The correct calibration of such an advanced plasticity model, and especially its plastic potential, will be subjected to a further research.
