Abstract | One of the failure modes in tube hydroforming (THF) is bursting. To predict the burst pressure in the THF process, Brozzo's decoupled ductile fracture criterion was used in conjunction with a dynamic nonlinear commercial finite element software, Ls-Dyna, and the criterion was evaluated using the data obtained from the free expansion (tube bulging) tests performed on 0.9 mm and 1.2 mm thick stainless steel (SS) 321 tubes. The predicted burst pressures were compared with the experimental results for both thicknesses. The predicted burst failure of the tube bulging, based on the Brozzo's criterion, demonstrated a good agreement with the experimental data, indicating that the present approach for predicting the burst failure for the tube bulging can be extended to predict formability limits in THF applications. © 2011 American Institute of Physics. |
