Based on the fundamental theory of highly nonlinear solitary waves (HNSWs), three transducers embedded with PZT circular materials are investigated, and designed for the nondestructive testing (NDT) of the Young’s Modulus of materials. Three different materials, including Teflon, granite and stainless steel, are tested by the transducers. The testing results show that the differences among transducers are below 0.5%, and the ratio between standard deviation and average value for single transducer is below 0.4%, which proves the high consistency and repeatability of the three transducers. The deviations from the theoretical analysis and the three materials are below 3%, which confirms the accuracy and reliability of the transducers. By comparing the results of Ultrasonic Pulse Velocity method, the HNSWs based transducers are more affordable, accurate and reliable.
