Modelling wear in Abaqus 1

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.

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?
 
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
