Abstract
The measuring of elastic modulus based on ultrasonic is the key to improve the propagation time measurement accuracy. In addition to the use of advanced equipment and software algorithms, the error of measurement time caused by the acoustic coupler interface can be completely avoided by use of step-axis specimen. Using time interval between primary and secondary pulses can effectively eliminate the extra delay.
