AIP Conference Proceedings Vol. 2051. P. 020152-1-020152-5Abstract: Numerical modeling of spalling brittle fracture along the (0001) plane in a zinc single crystal under shock loading by an aluminum projectile was performed in the work. Numerical modeling was carried out by the finite element method in a three-dimensional statement. The mathematical model allows to take into account the anisotropy of bulk compressibility in a single crystal of zinc, auxeticity, anisotropy of the propagation velocities of elastic longitudinal and volume waves. Stresses are determined on the basis of a comparison of velocity profiles of the rear surfaces of targets from zinc single crystal in mutually perpendicular directions when it is destroyed along the (0001) plane in natural experiments and numerical simulation.
