Impact behavior of a novel fiber metal laminate based on ultra-high molecular weight polyethylene fiber composite and aluminum sheets is investigated using a comprehensive finite element modeling procedure. A user-defined material subroutine based on continuum damage mechanics is developed. Cohesive zone model is implemented to simulate the inter-laminar damage. High velocity impact simulations showed similar modes of deformation and failure to that observed in experiments, and provide a good approximation for residual velocity against spherical and conical projectiles. The results show that the lay-up sequence is effective on the ballistic behavior of the target exposed to the spherical projectile; but, has little effect if a conical projectile is used.

Abstract
Impact behavior of a novel fiber metal laminate based on ultra-high molecular weight polyethylene fiber composite and aluminum sheets is investigated using a comprehensive finite element modeling procedure. A user-defined material subroutine based on continuum damage mechanics is developed. Cohesive zone model is implemented to simulate the inter-laminar damage. High velocity impact simulations showed similar modes of deformation and failure to that observed in experiments, and provide a good approximation for residual velocity against spherical and conical projectiles. The results show that the lay-up sequence is effective on the ballistic behavior of the target exposed to the spherical projectile; but, has little effect if a conical projectile is used.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
