Description:     Comparison of MAT_224 (*MAT_TABULATED_JOHNSON_COOK) with 
                 reliable implemented material laws in LS-DYNA,
                 MAT_024 (*MAT_PIECEWISE_LINEAR_PLASTICITY) and 
                 MAT_015 (*MAT_JOHNSON_COOK). Example contains elementary 
                 single solid elements in comparison with these materials.
                 The development of MAT_224 is funded by the FAA.
                 Four load cases:
                 - Load case 1: Uniaxial tension, orthogonal directions free
                 - Load case 2: Uniaxial tension, orthogonal directions hold
                 - Load case 3: Uniaxial tension, orthogonal directions hold
                   and released after 2.5 seconds
                 - Load case 4: Uniaxial tension, orthogonal directions 
                   hold after 2.5 seconds
                 In particular verify the influence of thermal softening
                 and stress triaxiality
