We apply an innovative experimental approach based on ultrasonic immersion tests for the characterization of the elastic response of a multi-layered anisotropic GFRP composite. The good agreement between the results of the nondestructive measurements and the results of standard destructive mechanical tests shows the effectiveness of the proposed experimental setup. Moreover, the accuracy of the ultrasonic...
A simulation of open source code is presented for elastodynamic wave propagation of wide-band pulses from arbitrary transducers configuration in viscoelastic media. The code utilizes the well known Elastodynamic Finite Integration Technique with an added dissipative term. It manages a programming interface with MATLAB and a GPGPU acceleration code for openCL capable devices. This paper presents a...
In this paper, the layered structure ZnO/Quartz (90deg rotated ST-cut) is investigated theoretically and experimentally. Both waves, Rayleigh and Love, are analyzed. Dispersion curves of phase velocities, electromechanical coupling coefficient (K2) and temperature coefficient of frequency (TCF) were calculated as a function of normalized thickness ZnO film (khZnO = 2pihZnO /lambda) and the optimum...
