| Abstract: | In this paper, the nonlinear stress wave in axial symmetry tube was
investigated by using strange perturbation methord. The approximation of
(?)_r being small in literature 3] and 4] was removed during obtaining
basic equations. In the limit of long wave, the nonlinear stress wave in
the tube satisfies Korteweg de Vries equation. |
