- •
Accurate determination of the elastic constants according to elastic wave theory.
- •
To investigate the feasibility of free edge sensor placement for extracting more vibration modes.
- •
The relationships between the sensing locations, impact locations, and intensities of modes are investigated in detail with the aid of the mode shapes.
- •
Influences of the multiple modes and liquid level variations to the frequency responses are investigated.
- •
This work also provides related experimental evidence for complicated fluid-structure interaction (FSI) problems for three-dimensional solids.
