Contact force from simulation is higher by about 2000 N

Hello, 

I am working on a simulation of Rivet installation. Everything is modeled with solid elements. The rivet is with Elform 14 and rest of the parts are with Elform 24. I am comparing results to experimental data. I am comparing to load versus deflection curve. I am getting the same shape curve but the load is 2000 N more from simulation. 

I tried contact type 7, Type 19 and Type 25. In all cases I get the same result. (CONTACT PARAMS ARE BASED ON RECOMMENDED VALUES)

The simulation was also run with LS-DYNA (in the same published paper) and they obtained the same result as experiment. 

Please see attached result of my simulation.

Any suggestions and help is appreciated.

Thanks!
