Energy trapping of thickness-shear vibration modes in a partially electroded piezoelectric crystal plate of monoclinic symmetry is analyzed. Effects of piezoelectric coupling on energy trapping are examined. Results show that the effect of piezoelectric coupling is comparable to the effect of electrode mass and needs to be included in the analysis of energy trapping.
