The paper deals with numerical modeling approaches of a steel projectile impact on composite plates. Currently, vehicle ballistic protection is achieved predominantly using metal-based armor which is heavy and thus negatively affects other vehicle parameters, such as maneuverability. Another option is to use a composite or hybrid sandwiches. To speed up the design of such elements for ballistic protection, it is appropriate to use numerical simulations which allow for a reduction of the numb er of experiments required to select appropriate alternatives for the construction features of ballistic protection. For this reason, different numerical mod els describing the penetration of a composite plate by a steel projectile have been developed. These models are based on different damage criteria. Since there is no universal damage criterion, it is necessary to find suitable options as well as methods to identify parameters for different types of materials. Therefore, different possibilities to adjust these models to experimental data were investigated. The proposed models will be used in the development of high-quality composite sandwiches for ballistic protection.
