Numerical Simulation of Embedded and Co-cured Composite Damping Structure under Low Velocity Impact

摘要

Embedded and co-cured composite damping structure is a novel damping processing structure, which possesses excellent damping properties and mechanical performances. In this paper, explicit dynamic analysis software LS-DYNA is employed to simulate low velocity impact on embedded co-cured composite damping structure panels. To illustrate the validity of modeling and calculation method, the simulation results are compared with the experimental data. And the results show that the impact resistance of embedded co-cured composite damping structure is much better than composite panel without damping material.
