Abstract
In computing eigenvalues for a large finite element system, it has been observed that the eigenvalue extractors produce eigenvectors that are in some sense more accurate than their corresponding eigenvalues. From this observation, uses a patch‐type technique based on the eigenvector for one mesh quality to provide an eigenvalue error indicator for the complex problem of out‐of‐plane plate vibration analysis. Tests show this indicator to be both accurate and reliable.
