| Abstract: | This paper constructs the fundamental theory of finite element method of lines which is used in solving axisymmtrical problem of elastic mechanics. The present method includes the isoparametric finite element of lines with 2, 3 or 4 lines. Interpolating matrix method is applied to solve the two point boundary values problems along by the direction of lines. The computational results demonstrate that the finite element method of lines is accurate and its convergence is well. |
