Abstract: This study presents a detailed analytical characterization of the effective strain distribution in Kevlar composite subjected to high-velocity impacts. Using finite element simulation data, a quadratic polynomial model was developed to describe the variation of strain along the penetration path. The derived equation accurately captures the peak deformation occurring approximately 5 mm from the impact point, with a maximum strain of around 3.0. This model provides valuable insights into the localized deformation behavior and failure zones within Kevlar during ballistic events. The findings contribute to the optimization of composite armor design by enabling precise prediction of strain concentrations, thus enhancing the understanding of impact resistance mechanisms. This approach offers a novel, mathematically grounded method for analyzing impact-induced deformation in material.
Key words: Kevlar, ballistic impact, stress analysis, strain distribution, composite failure, deformation prediction.
