Ok but my point is precisely to have a formulae giving the attack value on the effective health and therfore not considering the armor.

I don't get something : the defender has 60armor and 1000hp. So his effective health is 1600.

His attacker has 60armor pen. Let's consider that the defender has 1600hp and 0armor.

Using the formulae you gave we have :

dmg_before_mod*(2 − 100 / (100 + 60))=dmg_after_mod

his effective health before armor pen consideration is 1600 so we have :

effective_health_after_pen=dmg_before_mod=1600/(2 − 100 / (100 + 60))=1163 not 1000, why ? I used the armor pen modificator considering his effective health only.
