Solution of Eigenvalue Problems as Extremes of a Second Degree Surface
Abstract
In this work the eigenvalue problem is formulated as an optimization problem of a second degree surface. Lagrange multiplier technique is employed, such that the eigenvalues and eigenvectors are exactly obtained. The obtained results agreed with that of the previous techniques. A flowchart and Matlab program are introduced to simplify the proposed technique. Further, the proposed technique is applied for vibration analysis of two different plate configurations.

PDFDisclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
