Abstract :
In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the
Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming
of a straight tube is simulated by finite element method and verified with published experimental data. This
adaptive simulation technique is based on the ability to detect the onset and growth of defects (e.g., bursting
and wrinkling) and to promptly readjust the loading paths. Thus, a suitable load path is determined by
applying Adaptive Simulation Method in ANSYS Parametric Design Language (APDL).
