Development of Acoustoelasticity in Japan

Abstract Rapid development of electronic devices made accurate measurement of time-of-flight possible for the elastic waves propagating in solid materials. Acoustoelasticity has been steadily used not only in laboratory measurements but also in industrial applications for residual stress measurement. Recent work of acoustoelasticity is introduced based on the results reported at the meetings of the working group for acoustoelasticity which was organized in the Japanese Society for Non-Destructive Inspection.
