Abstract

This article examines the methodological principles and experimental results for determining a new mechanical characteristic of solid media—the stress wave modulus. The authors describe an ultrasonic technique for measuring the propagation velocity of polarized shear (transverse) vibrations in prismatic metal, polymer, and rock specimens subjected to stepwise uniaxial loading and unloading. Based on the identified linear relationship between the change in elastic wave velocity and the level of mechanical stress, it is shown that the sign and magnitude of the stress wave modulus are determined by the elastic-plastic properties and material composition of the materials under study, remaining quasi-constant within the elastic limits.
