====== Drawbead analysis ======

  * Numerical simulation of an experimental drawbead device (used by H.D. Nine – General Motors - 1978)
  * Drawing and clamping forces are studied.
  * Frictional component can be avoided if the rollers are free to rotate.
  * Springback radius can be estimated and compared to experimental results
