Abstract |
|
We study the propagation of shear horizontal (SH) waves in the interfaces of an A/B/A piezoelectric structure with an electrical and mechanical imperfect contact, being modeled by means of a capacitor and a spring, respectively. The analytical dispersion relations are obtained and some limit cases are analyzed in detail, predicting the existence of interface waves. Based on numerical calculations, it can be shown that the electrical and mechanical imperfections strongly influence the dispersion curves. |
