Dear all
I hope you are fine. Can any onle please help me in a simulation problem. I am doing hot compression test simulation with 60% height reduction. One material is rigid 2 D wire which is compressing the material and joined by reference point. When I am applying 4 different temperatures then 4 different graphs obtained for force vs displacement on the reference point. but in interaction properties when I am applying different friction coefficient values from 0.1 to 0.5 then there is not any change of graph curves. Can any one please tell me what is the reason behind it. As if there is contact between two materials then there will be friction between them. By changing friction coefficient force displacement graph should be affected. I have attached the .cae and .jnl file with excel graph of force displacement for different temperatures and friction coefficient.
Thanks for every one.

For validate the software, I think that you need to test with the "Compression ring test". The sample have the following relation: 6 (outer diameter), 3 (inner diameter) and 2 (thickness). If you make the virtual test (with Abaqus), when you use friction factor =0, with the compresion of the sample, the outer and inner diameter increase (figure a). When you use friction factor greater, the inner diameter reduce its value (figure b).
Thanks Daniel
You are right. I have tried it by this way when there is no friction factor then deformation is different way and when there is friction factor then compression in different way.
I was trying to find the force displacement graph on the reference point but I think there is change of deformation shape on the right side nodes and element of the body.
