Removing failed elements from display
Removing failed elements from display
(OP)
Hello,
i have a problem with removing failed elements in abaqus. I am investigating the impact of a cylinder on a plate. The plate should be penetrated. I am using the Johnson-Cook-model and have assigned a value for "displacement at failure" under the option "damage evolution". I have also enabled the "element deletion" option and "status" in the field output menu. But the extremely distorted elements are still shown in the view port. Can somebody tell me what else i am supposed to do ? I have attached a screenshot of the problem so you can see what i mean.

See attached. Does that work? If not then maybe they haven't failed.

E modulus = 210 GPa
Density = 7850 kg/m³
poissons ratio = 0.33

I tried your material model and it worked fine for me. Elements are deleted. I am not qualified to comment on the material model's accuracy though.
I attached a test input file.
Oh yes, I made one modification to the "plastic". I might be using other units than you [mm, tonne, MPa].
Good luck!

All this settings are from a paper i try to remodel. It's also strange that you have not enabled the element deletion option in the mesh module but the elements are still being eleminated. I will now use your material definition and let the rest be same to see if its just a material definition problem.

I used the plastic definition that you showed in previous post. Element deletion is as you say (use default).
When I import your model it also says "Element deletion: Use default".
I just have one field output request. I think it just bacame 3 when you imported the model from .inp. Boundary conditions usually split up into as many DOFs that are constrained.
Could it be a problem with consistent units?
Should the displacement at failure be equal to 1 (Damage evolution suboption)?
RE: Removing failed elements from display
Displacement at failure is equal to 1 because that's how it's noted on the paper. Look for D_c
RE: Removing failed elements from display
Can you explain me please what this setting means ?
RE: Removing failed elements from display
Those settings are only to include the internal element surfaces. This will allow the wedge to make contact with all elements that comes in contact with its cutting edge. The surface "erodesurf" is a surface defined on all internal element surfaces. Remove it from the general contact and you will see why.
I actually got the idea from an impact analysis...
Cheers!
