Honestly, I am not an aerodynamics engineer and hence don't know much about these terms. Is it the correct way to go about it, considering am not considering aero centre and centre of mass? I am using different 'shear centers' (point about which twist moment is zero: an assumption considering its small compared to flapwise and edgewise moment) to apply these loads. This is basically done in order to replicate the same bending moment and shear force nature along the blade as derived from FAST (for maximum conservative value of flapwise moment in time series). Secondly, I am using these three component forces to apply point loads at different location in my Finite Element Model (FEM).
