PROJECTILE IMPACT MODELS OF COMPOSITE PLATES FOR NUMERICAL SIMULATIONS

Popis výsledku v původním jazyce

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 a?ects 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 number of experiments required to select appropriate alternatives for the construction features of ballistic protection. For this reason, di?erent numerical models describing the penetration of a composite plate by a steel projectile have been developed. These models arebased on di?erent damage criteria. Since there is no universal damage criterion, it is necessary to ?nd suitable options as well as methods to identify parameters for di?erent types of materials. Therefore, di?erent possibilities to adju
