Abstract

The acousto-optic-diffraction method was employed to measure the amplitude of ultrasonic shear waves in a glassy polymer, poly(methyl methacrylate). The frequency was near 400 kHz, which is typically used in ultrasonic fractography studies of this material. The waves measured have an amplitude of 104-105 Pa and the amplitude attenuates almost exponentially. The attenuation coefficient obtained is about 0.21 Np/cm.
