I have a 7m HAWT blade. I want to make static bending test on it.
I will draw these graphs
Force vs tip deflection
bending moment vs strain
Are these enough or there are some other phenomena to check within this test?

Probably you will need to add to that the torsion moment (plade pitch moment).
You will need to build a support that can allow you to apply both force and moment at a given hinge arm from the blade tip.

It depends on what you are trying to determine and what assumptions you make. Typically root bending and torsion moments versus tip bending and angular deflection are presented. Sometimes the in-plane (lead/lag) bending moment with in-plane tip deflection may also be useful.
