To increase the strength of parts made of polymer composites in aviation, reinforcement of the polymer composite with one or several layers of metal is used. This work is devoted to the modeling of the behavior of such composites under low-velocity impacts. This impact type is especially dangerous for polymer composites because of the barely visible impact damage (BVID). Simulation was carried out using a grid-characteristic method, and various destruction criteria (Tsai-Hill, Tsai-Wu, Drucker-Prager, Hashin, Puck) and different types of contact between titanium and polymer composite were considered.
