However, most of these investigations focused on the rotating beams or plates undergoing a prescribed large overall motion, where the effect of large overall motion of the reference frame on elastic deformation was considered but at the same time the beam's elastic deformation couldn't influence the large overall motion of the reference frame because the large overall motion is known a priori.
