Eigenvalue Analysis

1. General

The eigen value problem is the solution of

(ω2MK)=0

M and K are the mass and stiffness matrix and ω is the eigen frequency.

The eigenvalues and corresponding eigenvectors are solved using a truncated Lanczos method. The computational procedure is described in Section 3.2, (Bell, K., 1998).
