I've conducted FE analysis of composite structure as shown figure. However, the strain on the metal surface does not match the experimental values. I am new to FEM and I am having trouble understanding the cause of this. Interface1 is applied friction coefficient of 0.7, and Interface2 is applied friction coefficient of 0.3. I use Ansys mechanical.
Please accept my apologies for my poor English.
Hello!
It is a bit hard to answer your question without more context. Nonetheless, if the strain on the metal surface doesn't match the experimental values, then I would assume that either your contact definition or the friction coefficient between the two surfaces is not correct. However without more information it is difficult to provide more assistance.
I am curious, how did you measure the strain on the surface experimentally? And did you measure the fiction coefficient between those two surfaces experimentally?
