How to use

Open the SOM.m file and modify the input parameters to your needs. The loading conditions that can be modelled are:

• uniaxial load
• shear of a (111) plane
• arbitrary stress tensors referenced to the crsytal frame of reference

All calculations are performed within the m24.m function, which outputs the resulting stress states for individual slip systems and for each {111} slip plane. These results are then plotted into four different stress orientation maps:

• mS vs mE

• |mS| vs mE

• tau vs phi [-30 deg, 30 deg]

• 3D: |mS| vs mE vs mN
