That is exactly what happens. Of course the result will be different,
since (∫dus will be shear deformation at previous step, be it computed
in any way, us is the current shear deformation us):
Fs_tot=ks₁us=ks₁∫dus+ks₁Δus
Fs_incr =ks₀∫dus+ks₁Δus

(why do you need to modify friction coefficient? Isn't that supposed to
be somehow constant?)

ok. Good luck with that one.
