Stress_code
In the OES data block description, word 11 (stress_code) of the header record
determines the following:
• Octahedral (or maximum shear) or Hencky-von Mises.
• Stress or strain.
• if the strain is curvature or fibre.
Stress_code is a bit pattern and the bits numbered from the right are:
Bit Description
1 Hencky von Mises (on) flag
2 Strain (on) flag
3 Strain/curvature (on) flag
4 Same as bit 2
Therefore, stress_code can be one of the following values:
Value On bits Description
0 0 0 0 0 Stress maximum shear or octahedral
1 0 0 0 1 Stress von Mises
10 1 0 1 0 Strain Curvature maximum shear or octahedral
11 1 0 1 1 Strain Curvature von Mises
14 1 1 1 0 Strain Fibre maimum shear or octahedral
15 1 1 1 1 Strain Fibre von Mises
In the OQG data block description, stress_code can be one of the following values:
Value Description
0 SPCForce
1 MPCForce
