“…Considerable efforts of building analytic model to predict the BLV for composite laminates have been performed. Based on the assumption that the mean pressure provided by the target consists of two parts, namely quasi-static stress and dynamic stress; Wen (2000) proposed a theoretical model to calculate the BLV for composite laminates:…”

“…The BLVs obtained from simulation (using two methods), analytical equation (Wen, 2000) and experiment (Hoof et al, 1999) are summarized and compared in Table 4. It can be observed that the numerical results either method 1 or method 2 are greatly close to the experiment, but the analytical result is a little conservative.…”

“…Analytical study is a powerful tool to completely understand the damage and energy dissipation mechanisms of composites (Naik and Doshi, 2005). Analytical investigations for composite materials under low to high impact velocities have been carried out and several theoretical models have been also proposed by many researchers (Wen, 2000;Billon and Robinson, 2001;Naik and Doshi, 2005). Experimental study is another significant method because it is not only closer to the real physical process but also is the base of the other methods.…”

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. In this paper, an analytical model, which based on energy balance, is built to study the process of high velocity impacts on woven Kevlar composite laminates by a cylindrical projectile. Four different mechanisms, such as laminate crushing, linear momentum transfer and tensile fiber failure, and shear plugging, is absorbed by the laminate while impacting. Then, simplification of the model is done to obtain the residual velocity and ballistic limit. The analytical results are validated with the results of experiment, and the perturbation analysis is done to analyze the reason of error.
