manoj Kumar347 is on a distinguished road
HI all,
I am working on a project for the creep modelling of short glass fiber reinforced composites which possess anisotropic material behavior in Ansys Software. Here the Hills potential criterion needs to be validated for the tensile testing by applying effective stress instead of equivalent von mises stress in both 0° and 90° to the fiber orientations. I am including the material link for the hills potential yield criterion and some related files. Please give me some advice on how I can further continue my post processing including the effective stress and equivalent creep strain in my analysis result files. Your advice and help will be greatly appreciated.
with best regards,
Manoj Kumar Panthangi
