An Optimal Design of the Two-Staged Square Sectional Combined Energy Absorption Structure with Local Surface Nanocrystallization

Preface to the Special Issue on the Dynamic Behaviors and Energy Absorption of Materials and Structures

“…Zhao and coworkers [2] investigated the antisymmetric plate wave by involving linear defects in phononic crystals, providing insightful clues for the design of topological edge states. Xu and coworkers [3] proposed an energy absorption strategy by using the two-staged square sectional combined energy absorption structure with local surface nanocrystallization. Li and coworkers [4] performed a combined theoretical and computational study on the physical mechanism of multiple impact phenomena that occurred in impact hammer testing.…”
