Acoustic fatigue of polymer materials

Work on the development of experimental techniques and methods of testing materials under high-frequency cyclic loading are briefly reviewed. Certain aspects of the acoustic fatigue of polymer materials are examined. Future research trends are discussed.Institute of Polymer Mechanics, Academy of Sciences of the Latvian SSR, Riga.
