Hi all?

Recently I noticed upon plotting the material numbers for an FE model that, depending on the MATERIAL ID that I specify under the FRICTION tab in the contact wizard, either my contact or target elements will have a different material number than their underlying elements.

For example, volume 1 (which has material property set #1) is expected to come into contact with volume 2 (which has material property set #2). If I use the contact wizard to set up a deformable-deformable contact pair, set the MATERIAL ID = 1 and plot material numbers, the contact elements have material number 1 while their underlying elements have material number 2. Similarly, if I set the MATERIAL ID = 2, the target elements have material number 2 while their underlying elements have material number 1.

Im pretty new to contact analyses and although my solution seems to have worked out quite well I was under the impression that contact and target elements adopted the material properties of their underlying elements.

I guess Im wondering if I have been setting up contact pairs incorrectly, and how might I ensure that contact and target elements retain the material properties of their underlying elements.

Sorry If this question is overly-confusing. Its been a long day!

Thanking you,
Dave
