I have been trying to simulate a compression test on a Octet lattice structure. And, I want to go till it damages and in abaqus for damage initiation it is asking me to look for strain and stress triaxiality.

1) What does this strain I give depict?

2) How do I calculate Stress Triaxiality for the particular strain I give?

What will be the threshold value for this?
