On the analysis of variational method with application to the shallow shell equation

The purpose o-f this work is to apply the variational principle with Rayl ei gh-Ri tz method -for a system o-f partial di-f-f erenti al equations in elastodynamic shell structure, which can be represented as generalized eigenvalue problem Ax = XBx. A variant o-f the QR & QZ-algorithms that can be used to solve it. In this work a computer program has been developed using QZ-al gor i thm to -find the eigenvalues of the above problem.
