  Two Plates
  $
  $     Two small plates pulled apart with a specified velocity
  $
  $
  $  Model initially changed from lstc example to partially reflect
  $  paper by Matzenmiller, et al (ls-dyna conf 9/94) - 
  $  However, that proved to have lots of problems also, major differences
  $  include the material and element formulation (& units) 
  $
  $
  $  John D. Reid  2/23/95
  $
  $   3/8/96  Velocity is changed to be a little more realistic.
  $           From 2.4 mm/ms (94.5 in/s) to 0.3048 mm/ms (12 in/s),
  $             and instead of instantaneous, ramps to 0.3048 over 10 ms.
  $  Units: mm, kg, ms, kN, GPa, kN-mm
