The total Lagrangian formulation is employed for describing the exact Timoshenko\u2019s bending kinematics, whereas the torsion is modeled as an uniform torsion and uncoupled from the bending motion. The aerodynamic description is based on an unsteady 2D strip theory in the time domain with the Jones approximation for Wagner\u2019s function. In addition, a follower forces assumption combined with a simpli\ufb01ed stall model are assumed, in which the lift-curve slope is interpolated based on the experimental data available in the literature. Very good correlation between experimental and predicted aeroelastic responses has been obtained for a highly elongated plate-like wing structure with a ballast at the free end.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/02\/IFASD-2019-127.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Gefferson C.
