Abstract:

The level and shape of the FLSD are dependent on many factors, which in principle should be the same with the factors that influence the FLD. These factors can be grouped as follows: • the material properties and parameters: work hardening coefficient, initial value of heterogeneity, initial anisotropy, a.s.o. • the experimental conditions: strain rate, strain paths, a.s.o. In this study, the influence of the material parameters and properties is analysed.

Keywords:

forming limit stress diagram, work hardening coefficient, initial heterogeneity, initial anisotropy.
