I have stored damage values for each eigen direction in statevariables for VUMAT code in ABAQUS Framework.My Question is Can the damage values be displayed along the eigen directions?.

I have condition to follow :

At the inception of damage growth, the principal damage frame coincides with the principal stress tensor frame and the eigen directions may change at each time step until the first damage variable

D1 reaches a threshold value of 0.2. Then the direction of D1 is locked and the other directions D2, and D3

follow the eigen directions with the constraint to be perpendicular to D1. When the second damage

variable reaches the threshold value, the whole directions are locked.
