Paper Number: ISOPE-I-22-435
... of the modal expansion method to this new field. The wave field is addressed by boundary integral equation using free surface Green's function method and the structure deformation is approximated by structure vibration modes. Assuming small-amplitude wave and small structure motion, the coupling is achieved...
