In the present paper, an analytical model which simulates the damage process of carbon fiber reinforced plastics (CFRP) under high velocity impact is proposed. The simulation model is based on the finite element method, in which the damage is considered by using stress criterion, continuum damage mechanics (CDM), and cohesive zone model (CZM). The parameters of the stress criterion, CDM and CZM, such as tensile strength and interlaminar toughness, are determined by the experimental results of the static tests. The simulated damage agrees very well with the experimental damage observation.
