Fig. 2. Finite element mesh of a clamped piezoelectric bi-material notch with mechanical and electrical boundary conditions.

Fig. 3. The HSV phase portrait and the contour plot of the characteristic function ( δ ) = det[ ( δ )] defined in (10) for a PZT-5H/BaTiO 3 bi material notch. The points or intersections of the curves of different color give the searched exponents.
