This paper evaluates the available models and empirical methods that predict the extent of damages of turbine missile impact on composite and multiple barriers. A method of analysis is used in which the missile' s residual velocity after perforating each layer becomes the impact velocity for the next layer. Recommendations are made as to the most accurate models for barriers made of concrete and steel layers. INTRODUCTION Turbine missiles are irregularly shaped fragments that result from the failure or fracture of ste
