Correlating the plastic strain ratio with ultrasonic velocities in textured metals

A method for predicting the anisotropy of the plastic strain ratio from measurements of ultrasonic velocities is proposed. The calculations are based on the assumption that both the plastic strain ratio and the ultrasonic velocities display the statistical symmetries of the crystal orientation distribution function (ODF). The proposed formula is based on a theoretical calculation of the anisotropy of theR value and the ultrasonic velocities for 28 different textures.
