| Abstract: | The propagation parameters of ultrasonic vibrations in an orthotropic material with imperfect elasticity have been measured. The results of the measurements are used to calculate the complex stiffness characteristics, and the correspondence between the nature of the anisotropy and the adopted model is examined. The anisotropy of the inelastic properties is investigated.Institute of Polymer Mechanics, Academy of Sciences of the Latvian SSR, Riga.
