  Two Plates
  $
  $   - two plates, one on top of the other with an overlap
  $   - material is some type of aluminum (I believe)
  $   - contact is defined (auto single surface)
  $   - modified from the plate model of 1995
  $      * refined mesh
  $      * documentation cleaned-up
  $      * re-organized
  $      * non-essentials removed
  $      * 1 cross section defined through each plate
  $      * fully integrated shell formulation (elform = 16)
