First of all I am new in the community and I am not a native English speaker, so I apologize for any misunderstandings.
I have to perform a finite element analysis of an assembly.This is a static analysis. I have to study how a componet af a hydraulic crane subject to a remote force applied to its upper surface perform. This cast iron support is connected to an iron plate. I modeled the four upper washers, not the lower ones. The washers have a non-penetration contact with the support. The support has 4 non-penetration contacts with the iron plate. I individually defined 4 bolted joint restraints (standard or counterbore with nut) so I can find them listed beneath the connectors folder in the simulation manager tree.
I adopted the direct sparse solver for this study.
After the simulation, looking at the deformed assemby with 100x scale factor adopted, I can notice that the washers don't follow the holes in the support. Why? Should I put some other constraint in the simulation in order to have a more realistic behaviour of the washers? I don't even know if I have obtained valid stress values after this problem. What do you think? Greetings Luca
