<p>Advanced composite materials with strength-to-weight advantages and selected directional qualities are needed for modern warfare settings. Particularly, the ductile materials used in current armor cause significant deformation and enhance the ballistic limit V₅₀, the velocity at a 50% probability of penetration. This study delves into the simulation method and results of ballistic penetration of various composite armor panels. Using results from tests conducted to determine V₅₀ and secondary impact, the simulation aims to closely mirror test results and accurately depict structural responses, including damage modes and deformation behaviors. Full three-dimensional finite element modeling and three-dimensional/two-dimensional material assumptions are employed to realize detailed ply-to-ply and through-thickness damage, such as interlaminar delamination, to achieve a higher correlation with test V₅₀ results. With the ability to handle a wide range of composite materials, this study pursues the establishment of a simulation methodology that effectively predicts and minimizes test conditions.</p>
