Contact Issue

[Dave442]

Hi all,

I have performed an ABAQUS/Explicit analysis of two parts that come into contact. The first part (Part A) deforms in a non-uniform manner and comes in contact with the second part (Part B) to different degrees at different locations.

I would like to quantify the % surface area of Part A that does not come into contact with Part B. Also, if possible, I would like to quantify the size of the gap between the two surfaces where contact is not established? I have been reading the manual but cant seem to figure this out.

Any advice would be greatly appreciated!

Dave

If I have understood your problem correctly, you can obtain CNAREA for the contact area, and the gaps, you could do by measuring the distance between nodes in CAE viewer maybe?

Hope this helps.

Hi Yaston,

Thanks for your response. I should have mentioned however that the simulations were performed using orphan meshes and, as such, I cannot output contact area.

Also, I can measure gap distance in CAE as you mentioned but I would prefer to automate this procedure somehow if possible.

Plot COPEN for the gaps.

Hi corus,

Thanks for the reply but (I may be wrong here), as I am using ABAQUS/Explicit, I don't think I can request COPEN.
