Discussion: 'Exploring effective methods for simulating damaged structures with geometric variation: Toward intelligent failure detection' ( McAdams, D.A., Comella,D., and Tumer, I.Y., 2007, ASME J. appl. mech., 74, pp. 191-202)

摘要

The paper of McAdams et al. (ASME J. Appl. Mech. 74, pp. 191-202) explored two different approaches for damage detection in vibrating beams having both manufacturing variations in geometry and crack damage. One of the approaches, however has a significant error in its formulation. The effects of this error on the formulation and the analytical results are discussed.
