| 1. | Mróz M.♦, Jankowski Ł., Holnicki-Szulc J., VDM-based identification of localized, damage induced damping, EWSHM 2010, 5th European workshop on Structural Health Monitoring, 2010-06-29/07-02, Sorrento (IT), pp.988-993, 2010 Abstract: This paper presents and experimentally verifies a method for identification of structural damage. The work is focused on such damage types as cracks, delamination or excessive allowances, which may not cause significant stiffness degradation but induce noticeable additional damping. Damaged elements are located and the damage is assessed in terms of the damage-induced damping and also the stiffness degradation. The Virtual Distortion Method (VDM) is used for modeling of the modifications. Affiliations:

| 2. | Mróz M.♦, Jankowski Ł., Holnicki-Szulc J., A VDM-based method for fast reanalysis and identification of structural damping, WCSMO-8, 8th World Congress on Structural and Multidisciplinary Optimization, 2009-06-01/06-05, Lisbon (PT), pp.1-9, 2009 Abstract: This paper proposes a new approach for modeling and identification of damping in linear structures. The approach is based on the Virtual Distortion Method (VDM), which is a reanalysis methodology for fast modeling and identification of structural parameters. The VDM is extended in the sense of considering structural damping in frequency domain. The assumed damping model is a modified version of the proportional damping, which allows to distinguish between and to modify independently the damping properties of each element and in each degree of freedom. In this way, a precise formulation of the task of remodeling of damping is possible. Moreover, the proposed approach is used to state and solve the (basically nonlinear) inverse problem of identification of material damping by decomposing it into two linear subproblems.
