Abstract :
This study was carried out by converting a balance lord bending stress into a change of ultrasonic sound velocity distribution as an information signal using an ultrasonic side wave oscillator sensor under the nondestructive method. The changes in the side wave sound velocity which corresponds to the stress-strain were measured by Poisson´s ratio that varied with the amount of longitudinal strain using the Singaround Method.
