  • Method of measuring stress distribution in a solid body
    Patent number: 4399702
    Abstract: Two ultrasonic wave beams of different frequencies are emitted into a body under consideration from different locations on a surface of the body and a scattered wave beam created at a scattering point in the body by the interaction between the two ultrasonic wave beams is received. The emitting locations of the ultrasonic wave beams and the receiving location of the scattered wave beam are caused to scan. Thus, the stress distribution in the body is measured on the basis of the received outputs resulting from the scanning.
