ABSTRACT:
Stress in a substance is measured by utilizing the transfer characteristics of elastic waves, such that elastic waves input to a substance are displaced by the stress load within the substance. Waves input to the substance and output therefrom by transmission or reflection are compared by fast fourier transform analysis, obtaining a wave attenuation factor quantifying the magnitude of stress in the substance.
