Abstract
There is presented a computer-implemented method for modal analysis in the frequency domain of a physical structure, said computer-implemented method comprising obtaining free decay vibration response data expressed in the frequency domain for the structure, formulating frequency domain equations based on the free decay vibration response data and comparing two or more points in the frequency domain, formulating a single or multiple order eigenvalue problem based on the formulated frequency domain equations, and solving the single or multiple order eigenvalue problem thereby obtaining one or more modal parameters.
