The problem to be solved is the dynamic loading of a cylindrical
concrete specimen mounted between two long steel rods, a so
called Brazilian test (cylindrical specimen) in a split Hopkins
bar (two long rods).

L. Schwer's modeling consists of these TG files:

   Brazilian.run.tg        main TG file with analysis options

   material.defs           common material parameter definitions for use 
                           by either LS-DYNA or DYNA3D

   materials.dyna          DYNA3D material model definitions

   materials.lsdyna        LS-DYNA material model definitions; includes 
                           an example of inputs for a User Supplied 
                       	   Material Model (mat 48)

   interface.defs          DYNA3D or LS-DYNA contact interface definitions

   brazilian.geom          TG commands need to construct the mesh and
                           associated boundary conditions
