Are creep and damage mutually exclusive in abaqus with DP criterion ?
Hello,
I have been using Drucker Prager plasticity with creep to solve problems in crustal geodynamics. Now, I would like to improve my models by introducing damage mechanics.
I have noticed that damage and creep are exclusive with Drucker prager plasticity. Am I wrong ?
In this case, is there any way to couple both of them ?
Tank you for any advice.
To clarify my question, I am adding some details. If I consider a material with these properties:
*Material, name=Material-visco-plas-damage
*Elastic
2.6e+10, 0.3
*Density
3000., 200.0
3000., 1800.0
*Drucker Prager
30.0, 1., 30., 0.
30.0, 1., 30., 600.
0.01, 1., 0.01,650.
0.01, 1., 0.01,2000.
*Drucker Prager Creep
9.89937e-48, 3.1, 0.0, 00.0
.....
....
3.19947e-28, 3.1, 0.0, 2000.0
*Drucker Prager Hardening, type=SHEAR,dependencies=1
....
...
...
*Damage Initiation, criterion=SHEAR
0.00001, 0., 0.00000
0.00001, 0., 100.
*Damage Evolution, type=DISPLACEMENT
0.3,
I noticed that damage is not considered in a VISCO step neither in a COULED DISPLACEMENT-TEMPERATURE step.
Has anyone faced the same problem ?
Thanks
Any answer ?
Anybody has faced the same issue ?
