Mathematical simulation of fracture of ceramic obstacles in axially symmetric high-velocity impact

  • 41 Accesses

Abstract

Calculations were made by the finite element method of the high-velocity interaction of cylindrical steel strikers with ceramic obstacles in the range of impact velocities up to 1500 m/sec. A kinetic model of active type fracture was used for numerical simulation of fracture of the ceramic. Chronograms of the process and distribution of the isolines of specific volume of cracks at different moments of time are given. Features of penetration of ceramic obstacles with different initial impact velocities are described.
