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
