Modelling wear in Abaqus

Modelling wear in Abaqus

Modelling wear in Abaqus

(OP)
Does anyone have any experience modelling wear in Abaqus, e.g. surface profiles, debris generation and volume lost after 5 million cycles?  I have read some papers published this but wondered how much work is really involved and if this is something that abaqus is able to handle?

Thanks

I have just seen an exmaple in the abaqus manual....

3.1.8 Tread wear simulation using adaptive meshing in Abaqus/Standard

I will go through this.

That INP file only has the information posted at the end of this message so that's why you are not getting a full model.  I checked 6.8-1 and 6.9-EF1.  I would contact your tech support they may have the full version or suggest adding this onto another INP.  I hope this helps.

Hello

thanks Rob, just wondering did you write the section above or did you find this from another input file? and can I just add this to one of the input files?

Thanks

OptiEng,

That was in the file you posted.  Just open it with a text editor.  I think that Abaqus forgot to include the actual model information or you are suppose to add this to another INP.  I hope this helps.

RE: Modelling wear in Abaqus

Hi..

Look, i was reading about steady state transport, but really i don´t understand anything,

How can i generate the mesh? it is not clear..
i treid to run the input example one, but i don´t have the old one). Maybe It is very difficult.

Please help.

Thank you

Sorry mosab2, I am not sure what your asking? are you trying to run this same input file as posted above?

RE: Modelling wear in Abaqus

Dear OptiEng,

I was reading the abaqus manual for learn something about the analysis by steady state. it is about my big problem, two discs with its angular velocity, and i read that for this problem it is better do it by steady state transport.

The problem is that i can´t understant how can i generate the mesh (revolve), do do you have a simple example explaining it.

Thank you
