It's called "Young" modulus because it defines the Young's modulus of
the packing (modulo a constant factor)...

Benoit, see
https://www.yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Ip2_FrictMat_FrictMat_FrictPhys
for equations inside.
Instead of justifying the equations of this specific functor, I'd rather
ask: what contact behaviour do you want to simulate?
