This model utilizes a composite cantilever beam arrangement that provides the bending and torsional stiffness, cladding segments representing a NACA0012 geometry and an added slender body allowing for the control of the ratio of the torsional and flapwise natural frequencies . In the present paper we will focus on a series of stall flutter experiments, tracking the motion of the tip of the wing to capture post-critical oscillation modes. Following the work of Tang and Dowel, the associated nonlinear post-critical behavior, due to both dynamic stall and static deflection, will also be studied using a continuous model including the ONERA dynamic stall formulation for the unsteady aerodynamics. %G English %L hal-04070849 %U https://cnam.hal.science/hal-04070849 %~ X %~ CNRS %~ CNAM %~ X-LADHYX %~ X-DEP %~ X-DEP-MECA %~ GENIECIVIL %~ LMSSC-CNAM %~ IP_PARIS %~ IP_PARIS_COPIE %~ TEST3-HALCNRS %~ HESAM-CNAM %~ HESAM
