Hello!
Below is a figure of what I am struggling to compare. Standard friction contact defined between plates. 1st load step is preload, 2nd load step is shear load. I am checking dependency of friction change onto how shear load is distributed between bolts and friction at contact. For solid model it works good, summation of shear load measured at bolts and shear at contact friction gives sum of applied shear load. However, for shell model, it works differently: summation of shear load measured at bolts and shear at contact friction does not match with applied shear load. For shell model bolt 'sees' much more shear load than what is being applied.
Is there anyone who may explain why shell and solid model results are not similar?
