Processes of Thermal Relaxation in Viscoelastic Media Exposed to Ultrasonic Waves

Abstract

Results are presented from an experimental study of the processes of thermal relaxation in viscoelastic media under the action of ultrasonic waves. Silagerm 5020 1/3 polyurethane is selected as a model sample of a viscoelastic medium. A plane ultrasonic transducer with a cooled surface is used to heat the samples. Temporal dependences of the temperature distribution at different depths of a polyurethane sample are obtained and interpreted.
