Abstract：Embedded and co-cured composite damping structure is a new damping processing structure, which can be widely used in high-tech fields such as aviation, aerospace, high-speed train, etc. Explicit dynamic analysis software LS-DYNA was used to simulate low velocity impact on embedded and co-cured composite damping structure panels. The simulation results are compared with the experimental data to illustrate the validity of modeling and calculation method. The result of simulation shows that the impact resistance of embedded and co-cured composite damping structure is much higher than composite structure without viscoelastic damping material.
