Is there any way to pass the plastic strain components to ABAQUS subroutines, e.g. VUHARD? I'm wondering whether I could write a subroutine to calculate the equivalent plastic strain directly from plastic strain components.
I'm working on a dynamic simulation using ABAQUS/Explicit. The material is under a high-frequency loading and unloading, and large deformation is expected.
ABAQUS calculate the equivalent plastic strain in the rate form, which returned me an outrageous PEEQ value. Ironically, all the PE components seem correct.
My issue would be solved, if I could write a subroutine to calculate the equivalent plastic strain directly from plastic strain components.
Thank you very much!
Dear Ninggag
yes you can compute the total equivelent plastic strain from incremental plastic strain if you write user subroutine (e.g. UMAT)
let me know your progress
regards
In my opinion, PEEQ is the accumulated plastic deformation, which is the integration of equivalent plastic strain rate over time.
