Description

A steel bar subjected to four-point bending was instrumented so that various strains and sound velocities could be measured during elastic and plastic deformation on both the tension and compression side of the bar. During plastic deformation, the load was reduced several times before it was increased again. We present the acoustoelastic constants and the corresponding third-order elastic constants 1, m, and n in both tension and compression in the “as-treated” specimen and after various amounts of plastic deformation. The changes in various sound velocities with plastic deformation are also discussed.

Ultrasonic Studies of Stresses and Plastic Deformation in Steel During Tension and Compression
