This dissertation deals with equilibrium, stability and vibrations of twisted rods. First the model used (i.e. the Kirchhoff equations) is presented from two perspectives : (i) as a direct theory, the special Cosserat theory of rods, and (ii) as a 3D -> 1D asymptotic theory. The core of the text is dedicated to a relatively comprehensive study of equilibrium solutions of a clamped twisted rods with or without self-contact. Results are applied to DNA supercoiling and single-molecule experiments. Then the case of a rod with intrinsic curvature and twist coiled around a rigid cylinder is examined. The equilibrium equations obtained are applied to analyze biology related problems as the growth of a climbing plant around a pole and the secondary...
