|Summary||We use a robust high-resolution measurement system for tracking the displacement, velocity and acceleration of a ballistic projectile. In this study, the Enhanced Laser Velocity Sensor (ELVS) is used to characterize the high velocity impact behaviour of Kevlar (r) fabrics. The results are compared with the predictions of a numerical modelling software (TEXIM). The results highlight the critical role played by the boundary conditions on the response of the target. It is shown that prior to failure or perforation the model predicts the response of the fabric fairly well when compared with experimental data. Both correlation and differences are discussed, identifying current model strengths, and needs for future model refinement.
