Hello everybody,
I want to simulate a tensile test using "damage for ductile metals" and "ductile damage". ABAQUS requires three parameters:
-Equivalent fracture strain at damage initiation (a)
-stress-triaxiality (b)
-strain rate (c)
I have already seen Abaqus analysis user's manual (23.2.2), but there's no example.
Currently, I defined a 3D solid deformable and an elastic and plastic behavior. I do not understand how to select a first set of parameters for the "ductile damage".
** MATERIALS
**
*Material, name=Aluminum
*Damage Initiation, criterion=DUCTILE
(a), (b), (c)
*Damage Evolution, type=ENERGY or DISPLACEMENT?????????????????
*Elastic
7e+10, 0.33
*Plastic
1.5e+08, 0.
1.8e+08, 1e-05
etc.....
Does anyone has an example or an experience in this type of simulation? Thank you in advance for your help.
Regards.
