A standard drawbead is characterized by a specific height and by a certain number of radii.  HyperForm automatically computes the restraining and holding (closure) forces relative to the given geometry for the material defined in the model.  The standard drawbead provided in HyperForm is shown below.

HyperForm computes the restraining force per unit length for the standard drawbead and the material selected, as well as the force per unit length necessary for drawbead closure.  It can also detect a necking condition where the restraint due to the bead geometry is severe enough to cause the material to neck inside the drawbead.
