 Yes, you've got it right, almost.

 If you know the static strength and increase the load in proportion as you described very well, the beam should break right away.  If you do not increase the load enough, then you would have to wait for a fatigue failure, and you need a fatigue curve to determine time.  In general, if u r not interested in fatigue, I would just increase the load until static failure.
