Article type: Research Article

Authors: Nobari, A.S. | Ewins, D.J.

Affiliations: Mechanical Engineering Department, Imperial College, U.K.

Abstract: In this article the subject of model updating using the inverse eigensensitivity method that uses only eigenvalues in the calculation is examined. The problem of creating an underdetermined set of equations is studied and ways of preventing it are addressed.
