Abstract: The Third National Symposium on Explosion and Impact Dynamics for Young Scholars was briefly introduced and all of the scientific reports presented at this symposium were reviewed. The scientific reports include four invited talks, nineteen thematic invitations and seventeen topic invitations, which were divided into five research topics, i.e. Detonation and Explosion Dynamics, Structural Dynamics and Multi-scale High Performance Computing, Material Dynamics and Experimental Testing Techniques, Dynamic Mechanical Behavior of Composite Structures, and Energy Absorption Characteristics and Optimization Design of Lightweight Structures. The symposium provides an excellent platform for the young scholars in the Explosion Mechanics and Impact Dynamics to conduct academic exchanges, establish academic friendship and enhance academic cooperation, and it also plays an active role in the construction and development of the discipline.
