Separation of elastic energy under shock loading of cylindrical bodies from isotropic and anisotropic materials

Determination of the velocities of propagation of elastic waves, using ultrasonic methods to find elastic constants, imposes a restriction on the geometry of bodies. The paper shows the features of the propagation of elastic longitudinal waves in an aluminum cylinder under shock loading against a rigid wall, as well as in cylinders of anisotropic single-crystal zinc with different orientations of the single crystal symmetry axes relative to the cylinder symmetry axis. The features of the separation of the initial energy of cylindrical bodies into the energy of rebound from a rigid wall, the energy of secondary rebounds of separate parts from a rigid wall, and the energy of elastic deformation of cylinders made of isotropic and anisotropic materials (for example, single-crystal zinc) are shown. On the basis of the analysis carried out, the limits of applicability of various geometries of bodies for studying the propagation of elastic waves in them in order to determine the elastic constants are determined.
