A New Approach for Linear Eigenvalue Problems and Nonlinear Euler Buckling Problem

Abstract EN

We propose a numerical Taylor's Decomposition method to compute approximate eigenvalues and eigenfunctions for regular Sturm-Liouville eigenvalue problem and nonlinear Euler buckling problem very accurately for relatively large step sizes.

For regular Sturm-Liouville problem, the technique is illustrated with three examples and the numerical results show that the approximate eigenvalues are obtained with high-order accuracy without using any correction, and they are compared with the results of other methods.

The numerical results of Euler Buckling problem are compared with theoretical aspects, and it is seen that they agree with each other.
