Abstract Ceramics are extensively used in protective structures which are often
subjected to projectile impacts. During an impact process of a ceramic target by a
projectile, fragmentation occurs in both the target and the projectile. It is challenging to
simulate such events and predict residual mass and velocity of the projectile. In this work,
we attempt to use smoothed particle hydrodynamics (SPH) in LS-DYNA to reproduce
fragmentation of the target and the projectile and predict residual mass and velocity of the
projectile during a projectile impact of a ceramic target. SPH models for an alumina
ceramic tile impacted by a blunt… More >
