“…Figure 14 shows a damage cone in the impact zone at 10 s  for the 553-m/s case that is consistent with Gellert's model (Gellert et al, 2000). Similar to Section 3, the red color represents the distribution of the failure strains ( 1 failure  ), which demonstrates the average damage evolution in the transverse direction.…”

A numerical material model for composite laminate, was developed and integrated into the nonlinear dynamic explicit finite element programs as a material user subroutine. This model coupling nonlinear state of equation (EOS), was a macro-mechanics model, which was used to simulate the major mechanical behaviors of composite laminate under high-velocity impact conditions. The basic theoretical framework of the developed material model was introduced. An inverse flyer plate simulation was conducted, which demonstrated the advantage of the developed model in characterizing the nonlinear shock response. The developed model and its implementation were validated through a classic ballistic impact issue, i.e. projectile impacting on Kevlar29/Phenolic laminate. The failure modes and ballistic limit velocity were analyzed, and a good agreement was achieved when comparing with the analytical and experimental results. The computational capacity of this model, for Kevlar/Epoxy laminates with different architectures, i.e. plainwoven and cross-plied laminates, was further evaluated and the residual velocity curves and damage cone were accurately predicted.

Abstract. A finite element model was developed to study the damage mechanisms of composite laminates under high velocity impact conditions. Modified Hashin failure criteria were used for the fiber breakage prediction. Cohesive elements were defined between two adjacent layers in the target laminate for the prediction of delamination initiation and propagation during the impact. The strain rate effects were also considered for the composite stiffness and strength. By using the developed finite element model, the ballistic limit, V L, for a composite laminated target can be calculated, which was validated by the test data in the public literature.

“…In the study of thickness dependence on the impact response of glass fiber reinforced laminates, Gellert et al [4] found that the indentation phase is most significant. Naik and Shiraro [5] showed that the tensile failure of primary yarns and deformation of secondary yarns are the main components of the energy absorption mechanisms.…”
