In this paper, the finite element method is used to investigate the influence of matching layer on the center frequency and the frequency bandwidth when the borehole wall ultrasonic imaging logging transducer operates in the mud. Our numerical results show that the characteristic impedance and the thickness of the matching layer influence the resonance frequency and the harmonic peak. With the increase...
The finite element method (FEM) is used to simulate a multi-morph bender bar, which comprises an inert substrate having two pairs of piezoelectric elements attached to its two sides. The simulation shows that the multi-morph bender bar has a lower fundamental frequency than the trilaminar bender bar. The effects of geometry on its fundamental frequency and conductance are investigated, demonstrating...
