Calculation of energy. The absorbed energy for each block and for the whole MDB face should be calculated up to the point of peak deflection of the barrier. E = t1 F .ds n ∫t n mean Where: t0 is the time of first contact, t1 is the time where the trolley comes to rest, i.e. where u = 0, s is the deflection of the trolley deformable element calculated according to paragraph 6.6.3.
