Abstract:
Plastic flow curves and plastic yield loci are essential for the numerical description of plastic material behavior with isotropic hardening. The Bulge test is a suitable experiment to prevent the necessity for an extrapolation beyond the tensile strain and it gives additionally an approximation point for the yield locus under biaxial stress condition. Nevertheless an accurate evaluation strategy is necessary. It can be shown that the response surface algorithm with a full quadratic approach lea...     »
