Comparison of through thickness displacements and in-plane stresses of flexural waves at 30 kHz with varying the thickness of d35 PZT transducers as follows: 1 mm (red solid line), 0.5 mm (blue dashed line), and 0.1 mm (green dotted line). (a) Axial (x) displacement; (b) lateral (y) displacement; (c) in-plane shear stress.
