abstract

  • In this work, a numerical model for aramid composites is experimentally validated in terms of permanent
    deformation, energy absorption and damage mechanisms for ballistic applications. Novel experimental and
    numerical results of non-perforating ballistic impacts with blunt projectiles are presented. The resistance
    forces and absorption energy by the specimen are measured for different impact velocities. A post-mortem
    analysis of the failure mechanisms is performed using computed tomography and a profilometer device. The
    numerical model is used to analyse the influence of impactor mass and impact velocity below the ballistic
    limit.
