摘要：
Inclined loading conditions cannot be avoided and strongly influence the mechanical response of honeycomb structures. In present study, deformation modes as well as dynamic responses of hexagonal honeycomb structures undergoing non-ideal oblique impact loadings have been investigated considering as significant parameters of the load angle (ranging from 0 to 10 degrees) and the impact velocity (ranging from 3 to 70 m/s). Some new deformation phenomena and response modes have been observed. Evident influence of asynchronous loading as well as impact speed on the deformation mode evolution has been determined. Corresponding mode classification maps were constructed. The present study provides a significant advancement to the comprehensive understanding of the dynamic response of honeycombs, which could be used to develop more valuable guidelines for design purposes in cellular energy absorbing devices.
