This function allows the user to set process parameters for tubular hydroforming. The basic setup is similar to sheet hydroforming described in Section 8.3.4.4. For tube hydroforming, the user may use fluid flux to control fluid internal pressure. The setup interface is illustrated in Figure 8.4.6.

Figure 8.4.6  Hydroforming control parameters

The user needs to select Volume from the drop-down list in the Hydro mech field.

NO FLUX: Allow the user to specify fluid flux vs. time curve to control internal fluid pressure. The dialog box is illustrated in Figure 8.4.7.

Figure 8.4.7  Fluid flux dialog box

CONSTANT: Define constant fluid flux. The user may key in a constant fluid flux in Fluid flux input data field.

TIME VARIABLE: Define time variable fluid flux. The user may click Edit button to display the Load Curve dialog box described in Section 8.3.4.4.

FLUID FLUX: Define flux of fluid.

DENSITY: Define density of fluid.

BULK: Defines bulk viscosity of fluid.
