Hi,
I have a VUMAT for progressive damage of fiber composite but that only contains damage initiation. I want to add damage evolution in this sub-routine.
Is there anyone who can help me out solving this? I can provide the subroutine if you want?
Thanks
Does anyone know how can the plastic strain be greater than unity? Such as in the benchmark manual 3.2.10 Indentation of a crushable foam plate:
As I Know that the formula for True strain is
True Strain = ln(1+nominal strain)
and if we consider a compression process then nominal strain should...
Thanks for your reply.
Actually this is the dummy data I created to understand the concept only. I have a complete data series as well but same is happening for real data as I tried to convert it into log plastic strain using the formula (ln(1+nominal strain) - true stress/E), which means that...
Hi
I am really confused how to input the hardening values for crushable foam model. Abaqus wants to input the stress - strain values in hardening table as true stress and log plastic strain.
In Abaqus manual the formula for calculating log plastic strain is = ln(1+nominal strain) - true...
Hi,
I am currently facing difficulties in calibrating abaqus crushable foam model with my experimental results.
I think I am bit confused about what values needs to be input in the model.
Right now my elastic properties are: E=400 MPa, v=0 (because its crushing)
In plastic under crushable foam...
thanks for your reply.
But the thing i like in PDE is that you can run single line at a time and visually see it in abaqus cae.
infact you can also create a time lapse between execution of command and that what i want.
this operations are not possible with external editor because in that case...
Hi,
I am trying to use Abaqus PDE to run the abaqus CAE.
When i open abaqus cae, I go to file and open Abaqus PDE. But in Abaqus pde i found that the recording button is not available for recording.
Secondly when i write a script and run the code by pushing the play button, then i got following...
