Abstract

Polymer composites are reinforced with one or several metal layers to increase the strength of parts made of composites. This work is devoted to modeling the behavior of such composites subject to low-speed impact. This type of impact is especially dangerous for polymer composites, because it causes barely visible impact damage (BVID). The simulation is carried out using the grid-characteristic method, and various damage criteria (Tsai–Hill, Tsai–Wu, Drucker–Prager, Hashin, and Puck) and different types of contact between titanium and polymer composite are considered.
