- The yield stress shall be arranged in the following order: , , ,
, , , , , .
- The original paper documents a comprehensive procedure to determine hardening parameter .
Damage
The damage evolutions are identical to the original formulation but with different notations.
The final stress is calculated as
Tension Damage Evolution
Compression Damage Evolution
View and edit parameters to see how they affect the damage evolution.
