Dynamics of thin rods kirchhoff equations
WebThe Kirchhoff model provides a well-established mathematical framework to study, both computationaly and theoretically, the dynamics of thin filaments within the approximations of linear elasticity theory. ... The study of static solutions to these equations has a long history and the usual approach to describing their instabilities is to study ... WebMar 9, 2014 · The equations for the equilibrium of a thin elastic ribbon are derived by adapting the classical theory of thin elastic rods. Previously established ribbon models are extended to handle geodesic curvature, natural out-of-plane curvature, and a variable width. Both the case of a finite width (Wunderlich's model) and the limit of small width …
