 Implement plane strain tension for HGO model using VUANISOHYPER_INV
*****************************************
**
** Element types: c3d8, cpe4r
** Material     : Compressible HGO model (native and user defined)
** Types of test: Plane-strain tension/compression with orientation
** Results      : Tension / Compression
**           S11:  59.08  /  -46.43
**           S33: -8.258  /  -55.25
