and without corrugation.
Figure 6.11 shows the variation of load and mean load values of the box with
and without fixing part as function of displacement. The fixing part is noted to act as a
trigger, lowering the initial peak load value. The initial peak load decreases from 93 kN
in empty box without fixing part to 77 kN in empty box with fixing part. The effect of
