Numerical simulation on performance of embedded and co-cured composite damping structure under low velocity impact

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