| Abstract: | This paper presents a brief overview of the existing direct methods for the finite-element model (FEM) updating problem and reviews the recently developed ‘direct and partial modal’ approach for the partial eigenstructure assignment problem and the ‘eigenvalue embedding’ techniques for vibrating systems, in the context of the solution of this problem. |
