Lectures

Two Days Pre-Course: "Operational Modal Analysis: Background, Theory & Practice"

A two days pre-course in Operational Modal Analysis is planned for May 8th to May 9th.

Who Should Attend 

Engineers and researchers who have basic knowledge of modal analysis and who would like to expand their knowledge into the field of Operational Modal Analysis in order to be able to solve the problems when the excitation is unknown as in civil structures excited by wind traffic etc. or mechanical structures in operational conditions such as rotation.
