| Abstract: | Combined stress intensity field theory and cohesive zone theory, A new low-velocity impact damage model for composite materials is investigated in this paper. The numerical method is implemented via a commercial finite element code, Ls-dyna. The new low-velocity impact damage model is verified using analysis of cases. The results for the low-speed impact damage resistant composite materials provide a theoretical basis. |

| Keywords: | Composite materials Low-speed impact damage cohesive zone Finite element method |
