For each structure, 3 cases are considered corresponding to a load of 1kN in the directions x , y and z . To estimate the sti ff ness behaviour of each structure, the resulting displacement in the loading direction is averaged over the nodes where the load is applied. The discrepancies between the reference models and the 4 shell based models are presented in figure 9 for each loading case.
