Discussion of 'Damage Localization and Finite-Element Model Updating Using Multiresponse NDT Data' by Masoud Sanayei, Erin Santini Bell, Chitra N. Javdekar, Jennifer L. Edelmann, and Eugene Slavsky

摘要

Multiresponse parameter estimation requires measurement of the same subset of multi degree of freedom (MDOF) (p. 693, line 15 from the bottom), and includes both static and vibration measurements. However, types of sensors for static and vibration testing are different and optimum localization of sensors requires different locations for different sensors. The requirement to measure the same subset of MDOF's is not effectual.
