Hi,

I have problem with introducing internal contact boundaries. A model consists with two glass plate and two cylindrical objects (model-glass plate contact with cylinders). The cylindrical objects are transversally loaded by the upper glass plate. The cylindrical objects have different material properties so the assembly method was used. To introduce contact behaviour in between glass plate and cylinder, points were used following cylinder_roller_contact example (Structural mechanical module -verification model). When I convert all the objects into the solid internal contact in between two cylinders are disappearing. I tried several ways to get that boundaries as contact pair but couldn’t.

Any comment is greatly appreciated

Thanks

Hello, Nithila,

In your file, some material parameters (lam2, mu2, E1, nu1, lam1, mu1, BM4, SM4) are missing. Could you include them in the parameters list?

Jesus.

Hi Jesus,

Thanks for the reply. Please find the attach model in there I have include the missing parameters. I 'm not sure about the lam2 and mu2 but I put lam4 and mu4 which are relevant to the plastic material.

Hi Jesus,

Please find the attach model. I have include all the parameter you have asked.

Thanks in advance.
