Abstract

The traditional Miura-ori was optimized to Miura-ori with platforms by geometric parameters. Two types of impactors were used to conduct low-velocity impact experiments at two specific sites. The damage morphology, response characteristics, and failure mechanism under various energy were systematically investigated. The results reveal that the impact resistance of the node is better than that of the base due to crushing absorbing energy. The impact resistance of the Miura-ori with platforms sandwich structures to the flat-ended impactor is better than that of the hemispherical impactor at the node. Still, the performance at the base is the opposite.
