We present a preliminary study on aneurysm wall vibrations associated with turbulent-like hemodynamics in intracranial vascular sections. The specificity of our numerical model is to explore the fluid/structure coupling of the arterial flow and the wall mechanics to relatively high frequencies (100-500 Hz). Despite the computational cost of the couple FSI problem and its direct impact on the resolutions of the model presented here, our findings highlight an important mechanical interplay resulting in a complex, but characteristic, deformation of the arterial wall. We hope to stimulate discussions and further work towards this physiological process, which can potentially have important implications for cell signaling mechanisms.
