Main Research Directions

Integrating and intersecting blasting engineering with materials science, his research uses shock waves generated by explosive detonation to achieve precise strengthening of materials, targeting fields such as advanced energy devices and national defense and military equipment (explosive processing). He also studies fundamental theories including rock and soil fragmentation mechanisms in the near-blasting zone and multiscale response laws of materials under shock loading, and explores the fine propagation and damage mechanisms of shock waves in multiple media (impact dynamics), serving blasting engineering.
