How tough are the landing gear?

Slightly OT, but for our sim model I just calculated the
B757 main gear spring constant to about kx = 120.000 lbs/feet/gear
If someone knows the vertical compression/travel length of the strut,
I guess we could calculate the energy needed to make it hit "bottom"
and break something - which would be a combination of ROD and landing weight.
The heavier your landing weight, the less ROD the gear can take.

Have a look at this footage...and in particular the landing gear.
It completely compresses (maybe to the point of failure?) but then extends again, the aircraft then continues on its roll out, albeit with a catastrophic airframe failure.
Quite amazing.
