Abstract To study the impact resistance of a bionic corrugated sandwich structure inspired by insectelytron, numerical models of rigid projectile impacting 2A12-T4 corrugated plate were established using the finite element software ABAQUS, and validation was performed to analyze the effects of projectile nose shape and impact position on its damage characteristics and energy dissipation. The results show that the impact resis-tance of corrugated plate with impact positions are significant different, the node and base positions have the best impact resistance to ogival-nosed projectile, while the middle position has the best impact resistance to blunt-nosed projectile. The impact resistance of the corrugated plate is most affected by the impact position under the blunt-nosed projectile, followed by the hemispherical-nosed projectile, while the different positions of the corrugated plate show more balanced impact resistance under the ogival-nosed projectile. In addition, the damage pattern and energy dissipation distribution of the corrugated plate are affected by the impact position and the shape of the projectile nose.
