Abstract:

We present an asymptotic analysis of the three-dimensional problem for a thin linearly elastic cantilever \hbox{$\Omega_\varepsilon = \varepsilon\omega \times (0,\ell)$} as $\varepsilon$ goes to zero. By assuming $\omega$ simply connected and under suitable assumptions on the given loads, we show that the 3D problem converges in a variational sense to the classical dimensional models for extension, flexure and torsion of slender rods.
