Road hazard is a critical problem in tire application. Steel cord-rubber composite such as steel belt is used to reinforce the tire stiffness in architecture of the radial tire. The main function is used to protect penetrations due to foreign objects. In fact, the knowledge of this material is not well-established yet in particular damage mechanisms subjected to impact load. The principal objective of this dissertation is to study high strain rate behaviors, impact behaviors as well as damage mechanisms of the steel cord-rubber composite, allowing us to develop a perforation criterion. The experimental analysis and numerical simulations allow us to thoroughly understand the dynamic behaviors and damage mechanisms for instance high stain rate tensile characterization, drop-weight impact and indentation characterizations, damage observation etc... In order to develop a criterion capable of predicting the perforation of the steel cord-rubber composite, the drop-weight impact tests and indentation tests have been conducted. Finally, we propose the perforation criterion based on analytical approach and its validation for the steel cord-rubber composite.
