Article Synopsis
- Understanding energy loss in piezoelectric materials is crucial for manufacturers of acoustic transducers, as it impacts their efficiency.
- The power dissipation in these materials can be attributed to various factors influenced by the phase angles of mechanical, electrical, and piezoelectric constants, yet this separation relies on the type of constitutive equation used.
- This study highlights the complexity of identifying specific losses in piezoelectric materials, revealing that incorrect assumptions about material constants can lead to flawed piezoelectric models.
